3 Installation and Operating Instructions

WARNING

Gas detection and exhaust fan control are provide d by a M ac u rco DVP-120 system. System wiring includes the main power connection for the DVP-120, 4-20mA current loop and 24VDC power connections between the remote sensors and the DVP-120, the fan control connections and/or alarm connections from the DVP-120 to the building ventilation and automation syste ms. The DVP-120B also inclu des the RS-485 serial interface from the DVP-120B to the MRS-485 and remote detectors. Power to the MRS-485 and detectors is provided by isolated/remote low voltage power supply.

The system is configured by th e user throu gh th e LCD display and keypad. The sy ste m di s play pr ovides the user w ith the sy stem status and the status of each configured sensor. In addition, all control functions of the DVP-120 may be accessed through the system display and keypad.

This equipment helps monitor for the presence and concentration level of certain specified airborne gases. Misuse may produce an inaccurate reading, which means that higher levels of the gas being monitored may be present and could result in overexposure and result in serious injury or death. For proper use, see supe rvisor or U ser In struct ion s, or call Ma curc o Tec hnic al Serv ice at 1-844-325-

3050. This DVP-120 system should be used with Macurco™ transducers and each unit will measure the level of the target gas (i.e. CO, NO2,

EX, etc.) and provide this information to the DVP-120 over a 4-20mA current loop. The transducers operate on low voltage (24VDC). All power and signal connections for the transdu cers are pro vided from the D VP-120 control pa nel, via unshie lded four condu ctor cable. Fo r DVP-120B Modbus applications use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections. The DVP-120 control panel provides three relays which can be used for ventilation fan control or alarm signaling. These relays (SPDT - Form C) are for pilot duty only, capable of switching 10 amp loads up to 240 VAC. Main power wiring should conform to national and local electrical codes and may require separate inspections and certification. Contact your local building authority for further details.

DVP-120 may not function effectively below 32°F (0°C) or above 104°F (40°C). Using the equipment outside of this temperature range may adversely affect product performance and result in serious injury or death.

3.1 Mounting Holes

Mounting holes are provided in the DVP-120 case at the four corners. The top two are keyhole shaped so that the panel can be hung and then the two bottom screws driven to hold the panel. See figure 3-1. The panel should be mounted with sufficient space around the panel for access to Conduit entry holes provided on the top, bottom and right side of the panel.

Figure 3-1 Mounting Holes

WARNING

3.2 General Wiring Information

High voltage terminals (120/240 VAC) are located within the DVP-120, presenting a hazard to service technicians. Only qualified technicians should open the D VP-120 case and serv ice the internal circu its. Ensure power is r emoved from the DVP -120 prior to ser vicing the unit.

Figure 3-2 Typical Layout

With the exception of the safety ground, all field wiring is completed via modular connectors (provided). After wiring, simply plug the modular connectors into the matching connectors on the printed circuit board (PCB).

Note: It is recommended to always install with wires enclosed within the rigid metallic conduit.

3.2.1 DVP-120

The power and signal connections to the remotely mounted sensors should be size AWG18 (minimum) for short runs. Refer to Table 32 for recommended wire gauges. Four conductor cables may be used in all cases since the DVP-120 employs DC power for remote sensors to help prevent electrical noise from interfering with the sensor output signal.

Do not bundle sensor power and/or signal connections with other AC power cables to prevent electrical interference. If other AC power connections must be bundled with the DVP-120 sensor cables, the sensor connections should be made with two twisted pairs of the appropriate gauge, with an overall foil and braid shield. All shields should be terminated at the DVP-120 end of the cable only. A ground stud is provided near the bottom left corner of the panel.

3.2.2 DVP-120B

The power connections to the MRS-485 and remote mounted sensors and should be size AWG18 (minimum) for short runs. Refer to Table 3-2a for recommended wire gauges. The power for the MRS-485 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.

The MRS-485 adapter output is wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. It is recommended to always use twisted wires to reduce noise and allow for reliable data communication over greater distances. For best performanc e use sh ielded 3-cond uctor wire w ith one twist ed pai r pr oviding a pair f or sign al (A & B), common (COM) and shield ground (SHD) connections. Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections. The Macurco MRS-485 Modbus output is connected via a four-terminal screw type connector. Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.

The main power cable should be routed int o the bott om left c onduit entry. Ma curco re commend s a minimum w ire size of A WG18 and the wire insulator must be rated for 140°F (60°C) service. The modular connector will accept wire from 12 to 24 AWG. The safety ground wire should be secured to the ground stud at the bottom left of the cabinet with the lock washer and nut supplied. Use a ring terminal for the ground connection. Refer to Table 3-1 for DVP-120 power connections. The line and neutral wires should be stripped 1/4 in. (6.5 mm), insert the wire into the wire cavity of the modular connector and tighten the screw clamp. Ensure that the wire cannot be easily pulled from the connector. Plug the modular connector into AC~ on the PCB and ensure that it latches into the header properly.

3.4 Remote Sensor Connection

3.4.1 DVP-120

Each remote sensor is connected by a four-wire connection – two wires for DC power and two wires for the 4 – 20 mA loop connection. The sensors are connected to the control panel PCB with modular connectors, two sensors per connector. See Figure 3-5 for a view of a typical sensor connector. Refer to Table 3-2 for wire size recommendations.

Each 8-terminal sensor modular connector may be disconnected from the PCB connector to ease wire installation. The terminals will accept wire from 16 to 28 AWG. To install a wire, strip back approximately 0.25 in. (6 mm) of insulation and insert the bare wire into the terminal. Tighten the screw clamp and ensure that the wire cannot be easily pulled from the connector. Connector to sensor C1 through C12 correspondence to all 12 input channels.

Table 3-2 Recommended Wire Gauge

Typical coverage for CO, CO2 and NO2 sensors is 5,000 sq. ft. (464.5 sq. m), 900 sq. ft. (83.6 sq. m) for combustibles and other toxic gases (see the User Instructions for each sensor type for location and coverage details). Extra sensors may be needed near areas where people work, such as toll booths. Macurco provides only the control panels and sensors. Fans, relays, and other devices are provided by the contractor. See the appropriate building code for the size of fans and air changes per unit of time.

3.4.2 DVP-120B

A Modbus over Serial Line Cable should be shielded for best performance. The shield should be connected on each detector at SHD terminal and connected to a ground terminal or chassis only at one end of the bus. An RS485-MODBUS must use a balanced pair (for A-B) and a third wire (for the Common). For RS485-MODBUS, Wire Gauge must be chosen sufficiently wide to permit the maximum length (1000 m or 3281ft). AWG 24 is always sufficient for the MODBUS Data. Category 5 cables may operate for RS485-MODBUS, to a maximum length of 600 m 1968.5 ft. For the balanced pairs used in an RS485-system, wire with a characteristic impedance of higher than 100 Ohms may be preferred, especially for 19200 and higher baud rates.

Note: It is recommended to always use twisted wires to reduce noise and allow for reliable data communication over greater distances. Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections.

For best performance use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections.

3.4.2.1 Topology

An RS485-MODBUS configuration w itho ut repeat er has on e trunk cab le, alo ng whic h devi ce s are con necte d, dire ctly (d aisy cha inin g) or by short derivation cables. The trunk cable, also named “Bus”, can be long. Its two ends must be connected on Line Terminations. (see Line Termination - End of Line Resistor section). The use of repeaters between sev eral RS 485-MODBUS is also possible.

3.4.2.2 Length

The end to end length of the trunk cable must be limited. The maximum length depends on the baud rate, the cable (Gauge, Capacitance or Characteristic Impedance), the number of loads on the daisy chain, and the network configuration (2-wire). For a maximum 9600 Baud Rate and AWG26 (or wider) gauge, the maximum length is 1000m 3281ft. The derivations must be short, never more than 20m 65.5ft. If a multi-port tap is used with n derivations, each one must respect a maximum length of 40m 131ft divided by n.

3.4.2.3 Grounding

The Common circuit (COM) must be connected directly to protective ground, preferably at one point only for the entire bus.

3.4.2.4 Power Wire

All field wiring is completed via modular connectors (provided). After wiring, simply plug the modular connectors into the matching connectors on the MRS-485. The power connections to t he remotely mounted detectors s hould be s ize AWG18 ( minimum) for short runs . Since Macurco detectors are rated for operation between 12 and 24 VDC or VAC, the voltage drop between the power supply and the MRS-485 should not be an issue if the recommended power wire gauge guidelines below are followed. The terminals will accept wire

from 16 to 28 AWG. To install a wire, strip back approximately 0.25 in. (6 mm) of insulation and insert the bare wire into the terminal.

3.5 Interfacing Macurco Sensors

3.5.1 DVP-120

Macurco sensors with current loop outputs may be used with the DVP-120. See http://www.macurco.com Macurco gas transducers. See specific information on other manufacturer’s transducers.

Power connections to Macurco sensors used with the DVP-120 are polarity-insensitive (no polarity) since a bridge rectifier is connected to the power input terminals. All sensors used with the DVP-120 panel employ screw clamp terminal blocks for power and signal connections.

2. Plug the MRS-485 adapter into the empty socket.

3. Install the provided MRS-485 screw.

4. See the wiring diagram for wire connection.

Figure 3-9 MRS-485 Installation

3.5.2.1 Connection

The Macurco MRS-485 output is connected via a four -termina l screw t ype conne ctor. The MR S-485 adapter is wired in the standard 2W Modbus circuit definition wi th s electable buil t-in t ermin ating re sistor s at the end s of the RS-4 85 bu s. The pow er for t h e MR S-4 85 ada pte r is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.

Note: Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.

Figure 3-10 Modbus Wiring

3.5.2.2 Line Termination - End of Line Resistor

The MRS-485 and DVP-485B adapters are wired in the standard 2W-Mo dbus circuit definitio n with selectable bui lt-in terminat ing resistors at the ends of the RS-485 bus. The MRS-485 and DVP-485B adapters provide integral termination for the end of line resistors (EOL). The terminations use 4-pin connector (for MRS-485) and 3-pin (for DVP-485B) with a jumper to select termination: The user selects no termination or one of the two Modbus line termination options. The MRS-485 has two line termination options provided and DVP-485B adapters have 120-ohm termination options provided onboard.

Figure 3-11 End of Line Resistor

Place the EOL jumper on one of the following positions:

3.5.2.3 Determining EOL Use

At the baud rate of 19200 (default baud rate for Macurco MRS-485 and D VP-485) and with cables less th an 1,000 ft. in length, terminat ion resistors are not recommended.

At the baud rate of 19200 and with cables longer than 1,000 ft., termination resistors are recommended. It is recommended to use an RS-485 type of cable and 120 ohms for termination resistor.

An RS-485 network requires a 3-wire cable: a twisted pair and a third wire. It is difficult to tell whether shielding is required or not in a particular system until problems arise, so it is recommended to always use shielded cable.

When using termination resistors use only 2 resistors, one at each end of the RS-485 transmission line (i.e. 1 at the DVP-485B and 1 at the last/farthest MRS-485).

3.5.2.4 Using Other Baud Rates

For any other baud rates calculate when (at what length) termination resistors are required. Calculate the length as 1000 ft. divided by the ratio between the new baud rate and 19200.

For example, if new baud rate is 9600 1000 / (9600/19200) = 1000 / 0.5 = 2000 (ft.) Use termination resistors when cables are longer than 2000 ft.

For example, if new baud rate is 38400 1000 / (38400/19200) = 1000 / 2 = 500 (ft.) Use termination resistors when cables are longer than 500 ft.

Note: Other manufacturers may have different recommendations on wire length and EOL resistor usage.

At 19200 baud rate (default), 1000 ft or less and using RS-485 or Cat-5 type cable

At 19200 baud rate (default), more than 1000 ft and using RS-485 type cable

3.5.2.5 DIP Switches and Addressing

Each MRS-485 (and the partner gas detector) must be configured to a unique address. If there are 10 detectors on the serial lin e, t hen 10 unique addresses must be used, one for each detector. To set the address, use the eight DIP switch positions. For each unit choose the value from 13 to 99 (see chart) and set the eight switches to match the address. UP means ON or 1 and DOWN means OFF or 0. For example, to configure a unit as address “50”, set switches “2, 5, 6” (see table) to ON or in the up position (01001100). See page 11 for a list of applicable addresses and dip-switch settings.

3.5.2.6 Normal MRS-485 Operation

The MRS-485 will monitor the 4-20 mA current output of the detector. At power up and during its warm-up period, the 6-Series detector will communicate its sensor type over the 4-20 current output using a custom protocol. The MRS-485 will automatically register each 6Series detector as it is programmed with information about all the detectors to which it can be connected. The MRS-485 will use this information to determine the gas level sensed by the 6-Series detector by measuring the 4-20 mA current-loop output during normal operation of the detector.

• When the LED is solid GREEN, the operation is normal, the MRS-485 knows the detector type, no errors are detected and no MODBUS data are being received or transmitted over the RS-485 line.

• When the LED is GREEN with random bursts of AMBER, the operation is normal and now data are being received or transmitted over the RS-485 line. The AMBER LED will come on anytime that there is data traffic

4.1 Initial Operating Mode

When power is first applied to the DVP-120, a few simple self-tests will be performed, and the system will cycle through all status lights, and display the system model and firmware version number (Figure 4-1). The system will then proceed to normal mode if the operating parameters have been entered.

Figure 4-1 Model Display

Each time the unit is turned on it performs a self-test, which activates the audible and visual alarms . If the self-test fails, or all the alarms do not activate, do not use. Failure to do so may adversely affect product performance and result in serious injury or death.

If the user has not entered any parameters, the system WILL NOT be controlling the ventilation system. The relays WILL NOT actuate, and the horn and strobe outputs WILL NOT be powered. The power status light will show NORMAL (steady green) and the system will immediately enter the CONFIGURATION mode, see section 4.2 for details to set the configuration parameters.

If a valid set of configuration parameters have been entered, the panel will wait for all sensors to warm up. During this time, the display will show a count-down, minutes and seconds, until the end of the warm-up period, (Figure 4-2).

Figure 4-2 Warm=Up display

During the warm-up period, the keypad will be locked. When the warm-up period ends, the LCD will start showing the normal display.

4.1.1 Status Light Display

The POWER, ALARM/WARNING, SILENCE, RELAY 1, RELAY 2 and RELAY 3 status lights indicate the system status and provide the following data:

• POWER

o Green (steady) – Power is good and there are no trouble indic ati o ns o Yellow (steady) – Trouble is indicated by a transducer or the panel itself

• ALARM/WARNING

o Off – All indicated gas levels are below the warning level o Red (steady) – One or more gas levels are at or above the alarm level o Amber (steady) – One or more gas levels are at or above the warning level

• HUSH

o Off –There are no silenced alarms or warnings o Red (flashing) –There are alarms, warnings and/or troubles that have been silenced (gas levels may or

may not remain or continue to be at an alarm or warning levels)

• RELAY 1

o Off – Relay 1 is not on o Green (steady) – Relay 1 is on

• RELAY 2

o Off – Relay 2 is not on

o Green (steady) – Relay 2 is on

• RELAY 3

o Off – Relay 3 is not on o Green (steady) – Relay 3 is on

The overall system status is visible at a distance via the status lights as described above. More detailed system information is displayed on the LCD, which can show the status of each relay and sensor. A typical status display is shown in Figure 4-4.

4.1.2 User Interface

The LCD display is used to show detailed information about th e status of the contro l system and the configuration parameter s to the user. The keypad is used to select the information displayed and to enter the configuration parameters, which are stored in the DVP-120 memory. The keypad consists of the usual ten-digit keys, four direction keys, plus a MENU key that is used to access the configuration menu and a HUSH key that will silence the audible alarm indicators. In normal mode, holding the zero key for three (3) seconds can be used to lock the keypad against accidental (or unauthorized) use. See Section 4.5 for details.

Figure 4-3 Keypad layout

4.1.3 Cursor Keys

In normal mode, (no warnings or alarm s ind icat ed), the up an d d own cur sor ke ys wi ll s crol l the d isplay to an y con figure d s ensors’ stat us . In normal mode, the left and right cursor keys will scroll through the status of each of the relays. When the left (or right) key is used to scroll to another relay, the display will remove the underlining under the sensor number and underline the relay number; this indicates that the digit keys can be used to jump directly to a par ticular relay’s stat us. When the up or d own key is again used the di splay will switch back to the digit keys jumping to a particular sensor.

4.1.4 MENU Key

The MENU key has three functions. First, when the system is presenting the normal display, pressing the MENU key will cause the system to shift to the Configuration Menu. The second function of the MENU key is to return to the next-higher menu level, e.g. from the sensor configuration menu to the system menu, or from the system menu out to normal mode. If in the middle of entering a multi-digit parameter, the MENU key also cancels any changes to the parameter. When the MENU key is used to return to normal mode, any changed configuration parame ters are saved in the DVP-120 ’s memory. The third function of the MENU ke y is to chang e the LCD contr ast by holding the MENU key for five (5) seconds, at which point the LCD will prompt for further activities, see sections 4.4 for more detail.

4.1.5 HUSH Key

The HUSH key is only used to silence the audible indicators (internal buzzer and possible external Horn and Strobe devices). Pressing and releasing the button will silence the internal buzzer. The HUSH button must be held for 3 seconds to silence the Horn and Strobe devices.

The display shows the day of the week and the time of day, in 24-hour format. It also shows the status of one of the relays, R1 in this example, and the type and indi cated the gas concentration of one of the configured sen sors , S 01 is a C O sen sor ind icatin g 5ppm i n thi s example.

Notice in Figure 4-4 that the digits 0 1 are underlined; this indicates that the digit keys can be used to jump directly to another sensor’s status. When the first digit is pressed, the display will prompt for the second digit of the target sensor.

Figure 4-5 Sensor Prompt

In this example, the first digit entered was 1. Since the DVP-120 can handle 12 sensors, the first digit for a sensor number is either 0 or

1. The leading zero must be entered when selecting a sensor less than ten. When the second digit is entered, the normal display will be restored; showing the type and value of the selected sensor. As mentioned above, the left an d right scroll keys will display the next or previous relay’s stat us. The display w ill also change the und erline to indicate that the digit keys (zero, one and two) can be used to jump directly to a particular relay. Since only one digit is needed to select a relay, the system does it immediately rather than prompting to show the relay.

If the sensor is indicating a gas level that is great er than the alarm or warn ing leve ls, the g as reading will altern ate wit h the word s ALARM or WARNING as appropriate. If a sensor fails, a connection is lost or the panel itself detects a failure of its own, the panel will enter TROUBLE mode and the gas reading will be replaced by the word TROUBLE (the TROUBLE status condition is discussed in section

4.1.6 Trouble Status Display

4.1.7 ALARM Status Display

When any sensor indicates a gas level that is at or above the configured alarm level for the sensor, the panel will enter ALARM mode, during which the internal buzzer will sound, the alarm lamp will be red and the LCD will show the sensor type and channel number.

Figure 4-6 Alarm Display

The display will cycle through all sensors that are signaling alarm levels, at five seconds per display. Pressing any key (except HUSH) will advance the display to the next sensor that is signaling an alarm level.

If Relay 1 is configured as an ALARM relay, it will be turned on when an alarm condition is recognized.

4.1.8 Warning Status Display

When any sensor indicates a gas level that is at or above the configured warning level for the sensor, the panel will enter WARNING mode during which the internal buzzer will sound, the alarm/warning lamp will be amber, and the LCD will show the sensor type and channel number.

4.2 Ventilation Control

The ventilation control functio n operates in dependentl y from the alar m function. It pr ovides the abi lity to config ure the DVP -120 for control of one to three zones. Each zone can respond to gas levels indicated by one or more of the sensors, with configurable turn on and turn off concentrations (rising and falling) for each gas type. Each zone can also be controlled based on the time of day.

Each zone can be configured to control one, two or all three of the relays and the external horn and strobe if desired. When more than one zone is controlling a relay it only takes one zone to activate the relay, but all controlling zones must release the relay before it will turn off.

Each of the relays, horn, and strobe has independent turn-on delays (to ignore short duration, transient gas signals) and turn off delays (to ensure minimum run times for fans that must run for internal cooling).

4.2.1 Zone Signal Display

When a zone is controlling the horn or strobe and they are activated, the panel will enter ZONE SIGNAL mode during which the horn and/or strobe will be turned on and the LCD will show the zone that is signaling.

As an aid when configuring the control panel, the first entry in the top menu summarizes the number of se nsor s and rel ays t h at the pane l is cur rentl y reco g nizing. B e sure th at the 4-2 0m A o utput on ea ch sensor is set to “On”.

Figure 4-14 Hardware Summary

The MENU key is also used to return to a higher-level menu and final ly ex it the conf igurat io n menus ba ck to norm al mode . When exiti n g from the menu system to normal mode, if any configuration changes have been made, the panel will ask whether changes are to be saved.

Figure 4-15 Save Configuration? Prompt

Pressing the zero (0) key at this point will cancel all changes except time and day of week. Pressing the one (1) will save all changes to memory, and the changes will then become effective in controlling the ventilation system.

While the DVP-120 is in the configuration mode, alarm and ventilation control functions continue in the background with the previously set configuration values. In particular, if an alarm condition is detected, the alarm lamp, the buzzer, the horn and the strobe will operate as configured but the LCD will not display the detailed information. The HUSH key can be used to silence any alarm, warning or trouble indicators without having to exit the configuration mode. If the MENU key is used to exit the configuration mode before using the HUSH key, the LCD will display the cause of the audible indicator.

The numeric keys are use d to change the part icul ar par amet e r di splayed. The un derl ined char acter, or spa ce, on e ach display, indicates what will be changed by the digit keys.

The left and right cursor keys will enter the particular submenu and scroll through the items of the same type where appropriate, e.g. enter the Configure Sensors submenu and scroll through the parameter lists for the existing sensors.

The up cursor key scrolls through the menu entries in the order listed here, while the down cursor key scrolls in the reverse order. Changing the configuration parameters requires the entry of a password before changes can be made. The default password is 1234. See Figure 3-21 for an example of the password prompt.

In many cases, the parameter is entered as a string of digits, but some parameters are selected by pressing a single key, e.g. pressing 1 selects Monday, 2 selects Tuesday, etc.

This display example shows that the time is 22:55 (10:55 PM). The underlined characters indicate that the numeric keys can be used to set the current time of day. When the first digit is entered (and after the password is entered if required), the display will change to show that the “hour” portion of the time is currently being entered.

In this example, the first digit entered was 1 (one), and the panel is waiting for the second digit of the hour to be entered. If the second digit is not entered within five seconds, the time will revert to the previous value. After the second digit of the hour is entered, the display will prompt for the “minute” entry:

Sensor Registration

Sensor registration is continuously monitored by the DVP-120 . When the currently selected s ensor type agrees with the stor ed registration information the DVP-120 will remain in normal mode. When new registration information is detected by the DVP-120, for example, if a different gas type of Macurco sensor was installed, the following message is displayed: “Configuration Changed Any key to save” is displayed.

Pressing any key will prompt the user to enter the password. Once the valid password is entered the new sensor type is saved. The program does not allow any other activity unless a valid password is entered.

If the DVP-120 is in configuration mode (user is changing the configuration) the registration information is saved in the background and the message indicating that configuration was changed is delayed until the user goes back to normal mode.

4.3.4.1 Relay Summary

Figure 4-30 Relay Summary This display example shows that Relay 1 is configured to operate Normally Off, with a turn-on delay and a minimum on time. Notice that the relay number, 1 in this example, is underlined. This indicates that the digit keys can be used to jump to a particular relay,

horn or strobe. The relays are numbers 1, 2 and 3; the horn is number 4 and the strobe is 5.

4.3.4.2 Relay Mode

Figure 4-31 Relay Mode

This display example shows that relay 1 is configured to operate in the Normally Off mode. The relay modes are:

• 1 ALARM

• 2 Normally Off (default)

• 3 Normally On

Relay mode 1 is a special case. This mode is only available on relay 1 and dedicates the relay to function as an alarm signal to a subsequent alarm or monitoring panel. This mode forces the relay to Normally Off mode with no turn on delay or minimum on time. See Section 4.1.7 for more detail regarding alarms.

Fail Safe operation can be implemented by configuring a relay to operate Normally On, and wiring the circuit using the NC (normally

closed) contact. In this way, if the control panel loses power the relay will turn on the controlled device if it still has power.

4.3.4.3 Relay Turn on Delay

Figure 4-32 Minimum on time

The default turn-on delay is one minute and the maximum allowed value is fifteen minutes. The value is entered in two groups, 2 digits for the minutes and then 2 digits for the seconds. A leading zero must be entered for each group if applicable.

4.3.4.4 Relay Minimum on Time

Figure 4-33 Minimum on time

The default minimum on time is one minute and the maximum allowed value is fifteen minutes.

4.3.5 Configure Horn Submenu

The configuration parameters for the horn are similar to those for relays. A horn would not normally require a minimum on time, but this parameter allows a more versatile configuration.

4.3.5.1 Horn Summary

Figure 4-34 Horn Summary This display example shows that the horn has been configured to operate with a turn on delay and no minimum on time. Notice that the horn number, 4, is underlined. This indicates that the digit keys can be used to jump to a particular relay, horn or strobe.

The relays are numbers 1, 2 and 3; the horn is number 4 and the strobe is 5.

4.3.5.2 Horn Turn on Delay

The default minimum on time is zero and the maximum allowed value is fifteen minutes.

4.3.6 Configure Strobe Submenu

The configuration parameters for the strobe are the same as those for relays. A strobe would not normally require a minimum on time but this parameter allows a more versatile configuration.

4.3.6.1 Strobe Summary

Figure 4-37 Strobe Summary This display example shows that the strobe has been configured to operate with a turn on delay and no minimum on time. Notice that the strobe number, 5, is underlined. This indicate s that the digit keys c an be used to jump to a par ticular rela y, horn or strobe.

The relays are numbers 1, 2 and 3; the horn is number 4 and the strobe is 5.

4.3.6.2 Strobe Turn on Delay

The default turn-on delay is one minute and the maximum allowed value is fifteen minutes.

4.3.6.3 Strobe

Figure 4-39 Strobe Minimum on Time

The default minimum on time is zero and the maximum allowed value is fifteen minutes.

4.3.7 Configure Zones Submenu

The DVP-120 ventilation control can support up to three zones. The zone functionality makes the DVP-120 very flexible. For example, each zone can be configured to monitor a separate set of four sensors and control a single relay.

Another control scheme uses one zon e to m onitor all sens or s and tur n one r e lay on at a r e la tively low g as c once ntratio n. A second zone monitors the same sensors and turns on a second relay if the gas concentration reaches a higher level. The third zone can also monitor the same relays turning the la st relay on as a signalin g devic e to a l ive monitor statio n, as we ll as turni ng on the extern al horn and strobe, under the assumption that the ventilation system is not working.

In addition to controlling the relays based on the gas concentration, each zone can have a timed function, e.g. turn on low volume ventilation fans at 7:00 AM and turn them off at 8:00 PM.

The default Ventilation Controls are:

• Zone 1 controls Relay 1

Z o n e 1 C o n t r o l s R 1 R 2 R 3 H 4 S 5

Z 1 G r o u p 1 N O 2 S e n s o r T y P e : 2

• Zone 2 controls Relay 2

• Zone 3 controls Relay 3

4.3.7.1 Zone Controls

Figure 4-40 Zone Controls

This display example shows that Zone 1 is configured to control all of the relays plus the horn and the strobe. Each of the relays, the horn, and the strobe can be removed from (or added to) the zones control by pressing the indicated digit key. By default, Zone 1 will control Relay 1, Zone 2 will control Relay 2 and Zone 3 will control Relay 3.

Definitions:

• Zone – Defines Sensor Input & Relay / Alarm Output

• Group – Set of Sensors of the same type and output within the same zone

• Average – Activation based upon an average of sensors in a group

• Voting – Number of sensors needed to be above trip point to activate the output

• Quorum – Number of sensors need to vote, 1 = any sensor

The digit controls are:

• 1 Relay 1 added/removed from the zone’s control

• 2 Relay 2 added/removed from the zone’s control

• 3 Relay 3 added/removed from the zone’s control

• 4 Horn added/removed from the zone’s control

• 5 Strobe added/removed from the zone’s control

When controlled by a zone the default horn pattern is the Triple Tap pattern, see 3.3.8.7 and the strobe will turn on continuously when a zone is controlling them.

Each zone can have up to three control groups defined. Each group either monitors a sensor type or implements a timer function.

4.3.7.2 Zone Group Type

Timed mode turns the zone’s outputs on at the START TIME if the current day is a weekday (or a weekend) and turns them off at the next occurrence of STOP TIME. The other thr ee mode s turn the outputs o n if the gas co nce ntration in dica ted by that t ype of sensor is at or above the Rising Trip Point and turns the outputs off if the concentration is less than or equal to the Falling Trip Point.

of all sensors in the group. Valid modes are:

• 1 Average

• 2 Voting (default)

When the configuration is Average, the gas concentrations from all sensors in the group are averaged and if the average is greater than or equal to the rising trip point the zone outputs(s) are activated. When the average is less than or equal to the falling trip point the zone output(s) is de-activated. If the average is between the two trip points, the outputs remain in their previous state.

When the configuration is Voting, the number of sensors in the group indicating a value greater than or equal to the rising trip point is counted. If the count is greater than or equal to the quorum then the zone output(s) are activated. If the count of sensors indicating less than or equal to the falling trip point is greater than or equal to the quorum the zone output(s) is de-activated. Activating the output(s) is given priority if a group has an equal number of sensors with gas readings greater than or equal to the rising trip point and sensors with readings less than or equal to the falling trip point.

5 BACnet

5.1 General Information

Following standard objects defined by BACnet are used in DVP-120B: a. Analog Input b. Binary Input BACnet objects available for each detector connected to DVP-120B are as follows:

5.1.1 Analog Input - Sensor ID

The value in the BACnet object refers to the Sensor ID/Type of Macurco Gas detector and value will have 6 trailing zeros e.g. for CM-6 value will be 1.000000. Values of 1 to 8 are only valid values.

5.1.2 Analog Input - Gas Reading

This represents the gas readin g of the detector . If the r eading is not reliab le then it w ill ha ve value 6553.5. The r eading may be unre liable for any of the following reasons:

• Registration Status of MRS-485 is non-zero (it is non-zero during detector warm-up period, trouble code, MRS-485

registration in progress, and other miscellaneous MRS-485 error indicated by red Status LED in MRS-485).

• A successful request/response has not been detected for the reading (i.e. a timeout occurred, or a detector does not

exist).

• The reading is under or over range DVP-120B compares the current reading of a detector with its range and anytime it

is outside the range, it will set the gas reading to 6553.5.

• Invalid Sensor ID Type (1 - 8 are the only valid values).

5.1.3 Binary Input - MRS Trouble

This binary input object is set (i.e. the value is 1) when there is an error in MRS-485.

5.1.4 Binary Input - Over Range

This binary input object is set when reading from the detector is over the range.

5.1.5 Binary Input – Trouble

This binary input object is set when the detector is in trouble condition.

5.1.6 Binary Input- DVP Com Error

If the panel stops making Modbus request to the detectors for a specified timeout period of 3 seconds, then a timeout event is triggered, and all gas reading is set to 6553.5, and DVP Com Error Binary Input data is set to 1. If timeout event is not triggered value is set to 0.

One way to find out Modbus Address and information type is to look at the value of the property “Object Name”. E.g.”S13 Sensor ID” meant address is 13 and information cont ained by BACnet object is “Sensor ID”.

5.2 Macurco Network Parameter Utilit y ( NPU)

Macurco Network Parameter Utility can be used to update firmware for IC used for BACnet functionality and BACnet configuration. To receive the latest version of Macurco NPU, as well as firmware and configurations, download the Macurco NPU from our website

http://www.macurco.com/downloads.html

connected to the DVP-120B. NOTE: Macurco NPU cannot use to upload DVP-120 firmware. Figure 5-4 shows the screen of NPU software when a device is connected. As shown in the Figure, it displays the device name with

device configuration version under it. Fields greyed out are read-only. Only protocol available as of now is BACnet MS/TP Server. Address - The address of the device in the network.

If a newer version of firmware is available in the NPU you will be prompted to update when

Default baud rate - 38400 bit/sec. APDU Timeout - The time in milliseconds that the driver will wait for a response from a device after sending a request. A number of APDU Retries - The number of times the driver will retry a request when a response is not received.

Figure 5-4 NPU Home Screen

Device Name - the description assigned to the device. The device name must be unique across entire BACnet network and must be between 1 and 16 characters in length.

Device Instance - node’s instance number and must be unique across the entire BACnet network. The value must be between 0 and

4194302. Max Master - defines the highest allowable address (0 to 127) for MS/TP master nodes on the network. Any address higher than this

will not receive the token from the device. This value must be greater than or equal to device address. Set this field to 127 if the highest address on the network is unknown.

Reload button - Will load the current settings for DVP-120B. To change the settings (on BACnet end) in DVP-120B, change the parameter in DVP-120B and hit Submit.

IC (in DVP-485B PCBA) used to sniff Modbus data and output BACnet has two types of file.

• DUF File This file contains the configuration for the device, i.e. Macurco Modbus Mappings, BACnet mappings etc.

• ELF File

This is device firmware file (.elf file) which run on the CPU. When connected to Macurco NPU (Network Parameter Utility) software, the software will compare the ELF file versi on with the version loaded on the panel and prompt for an update if a newer version exists. The. elf file is downloaded with the NPU software from

http://www.macurco.com/downloads.html

5.3 BACnet Connection

The Macurco DVP-120B BACnet output uses a 4 wire RS-485 connection, Data-A, Data-B, Common, and Shield (optional). RS-485 connection for BACnet output is labeled ‘TB2’. This can be converted to USB, Ethernet and Serial connections with the use of corresponding conversion equipment. For this example, we will use a USB to RS-485 Serial Converter Cable.

5.3.1 Serial RS-485 to USB Wiring

Most converter cables are going to come with more wires than what is needed by the Macurco DVP-120B BACnet output. The extra wires do not have a termination point and should be secured and protected from shorting using tape or heat shrink.

• Connect the required Data A, Data B and Common (Ground), and shield (if available) to the 4 pin BACnet connector.

NOTE: The color code for your cable may be different than the one shown here, reference the user manual for your specific cable for accurate wiring information.

• Plug the USB connection into the USB port of your computer, install any necessary drivers for the USB to RS-485 Serial Converter cable.

• Open your BACnet Software Solution and verify the Macurco DVP-120B BACnet Panel is communicating with the software.

5.3.2 Serial RS-485 to Ethernet (TCP/IP)

There are converters available to take the RS-485 BACnet output on the Macurco DVP-120B Control panel to an Ethernet TCP/IP connection. Follow the wiring diagram for your specific Serial RS-485 to Ethernet converter.

5.4 BACnet software

There are a number of software applications available to read the BACnet output of the Macurco DVP-120B Control panel. For more information on these please contact Macurco Support at 1-844-325-3050 or support@macurco.com

6 Troubleshooting

WARNING

The DVP-120/DVP-120B is tested at t he factory for reliable op eration. Most problems c an be traced to the set-up o f configurable feature s and modes, system wiring or trouble with the sensors.

Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument contains no user serviceable parts, and substitution of components may adversely affect product performance and result in serious injury or death.

6.1 System Status Light Flashing

The system status light (section 3 Operation) is normally green indicating power is present but will change to yellow whenever the controlling firmware detects a Trouble condition. Possible trouble condit ions are:

• Any configured channel has less than 4 mA flowing in the current loop.

• A sensor is reporting a trouble condition.

• Any configured channel wiring is open.

• Internal controller board problems are detected.

6.1.1 Input Channel Trouble

Any time the POWER light is y ellow, the f irst thing the technician sho uld consider is t hat one of the input chan nels is in trou ble. Reviewing the Sensor Status displays (using the up and down keys), should reveal which channel has a problem since the gas reading will be replaced with the word TROUBLE. Be sure that the 4-20mA output on each sensor is set to “On”.

6.1.1.1 No Sensor

A common source of a trouble condition is an input channel that is configured for a sensor that does not exist. In this case, the system expects to see current flowing within the current loop, but there cannot be current if there is no sensor connected. Either fix the misswired sensor or change the sensor type to NONE, section 4.3.3.2 Sensor Type the power light should return to steady green. Be sure that the 4-20mA output on each sensor is set to “On”.

6.1.1.2 Wrong Sensor Type

If all channels are configured properly, another source a trouble condition could be the type of sensor attached to an input channel. Macurco™ Toxic sensors can indicate high gas concentrations with signals of up to 24 mA in the current loop. However, a combustible sensor can indicate a trouble condition with a 21-mA signal. Therefore, a toxic sensor connected to channel which is configured for a combustible sensor can cause a fault indication if the gas concentration is high enough.

6.1.1.3 Sensor Trouble

All Macurco™ Sensors are e ither supplie d with a STA TUS la mp that will in dicate the he alth of th e device or will display a trouble condit ion on the digital display. Macurco sensors may be tested by depressing the TEST button on the sensor printed circuit board, or (depending on the type of sensor), the button on the interior front panel of the unit. Macurco sensors will step the output current level from 4 mA to 20 mA over the course of the w arm-up period, allowing th e techni cian to deter mine where the t rouble cond ition exists. If t he sen sor is still in a trouble condition, resetting the power may cle ar the troub le condi tion. R em ove one of th e powe r wires fro m the sensor terminal strip causing the sensor to go through a power-up reboot. Be sure that the 4-20mA output on each sensor is set to “On”.

6.1.1.4 Faulty Wiring

Finally, the wiring between the DVP-120 and the sensor should be investigated. The pow er input to the sen sor sh ould be i nvestigated at the sensor. Since Macurco se nsors are rate d for operat ion b etw een 12 and 24 VD C or VAC, the voltage drop betw een th e DV P-120 an d the sensor should not be an issue if the wiring guidelines in Table 2 2 are followed. A multimeter can be inserted to check the current flow within the loop, or a continuity test can be performed on all four wires between the DVP-120 and the sensor. Ensure power is removed from the DVP-120 prior to removing the input or out put conn ectors from th e DVP -120 controller b oard. Be sur e t hat the 4-20mA output on each sensor is set to “On”.

. After returning to normal mode (using the MENU key),

6.1.1.5 Resettable Fuse

WARNING

Each sensor channel is provided with a PTC-resettable fuse internal to the DVP-120 to protect against over current situations. To reset a sensor channel, power should be remove d from the ch anne l. This ca n be accompl ish ed b y remov ing power from th e se nsor – causing the loop current to go to zero, or by completely removing power from the DVP-120.

6.1.2 Internal Controller Board Trouble

If the sensor status display and investigative efforts reveal no problems with the input channel current loops and channel configuration, the most likely trouble condition is an internal problem detected by the DVP-120 controller. In this case, contact the Macurco Technical Support at 1-844-325-3050 for advice and help.

6.2 Timed ventilation problem

When using the timed ventilation mode, the system clock should be checked regularly (at least twice a year). The battery-backed real time clock in the DVP -120 does not adjust for daylight saving time so the spring and fa ll switch over poin ts are good c hoices to chec k the system clock.

6.3 No Power

The DVP-120 starts up as soon as power is applied to the microcontroller, and the DVP-120 is designed to have power continuously applied to the unit. An external indication of successful power application to the unit is the immediate operation of the Status Lamps grouped around the LCD. If the operator does not see an immediate response from the status lamps, power should be checked at AC~.

If the correct voltage is noted at AC~, then the internal fu se of the DVP-1 20 should be investigated. T he DVP-120 is protect ed from overcurrent and transient situations by the fuse at F3. After removing power from the DVP-120, F3 can be checked by removing the safety cover. If necessary, replace F3 with a 5x20 mm SLO-BLO fuse with a rating of 1 Amp 250V, e.g. Littelfuse P/N 218001. Be sure to Replace the Safety Cover on F3 before re-applying power to the DVP-120.

DVP-120 may not function effectively below 32°F (0°C). Using the instrument below this temperature may adversely affect product performance and result in serious injury or death.

6.4 LCD Display unreadable

It is possible that the LCD is unreadable due to temperature or aging of the control panel. If this is the case the following steps should rectify the problem:

• Hold the MENU key for three (3) seconds. After three seconds, the power led will turn red. After two additional seconds, the LCD backlight will also be turned off.

• Press the UP and DOWN cursor keys to change the LCD contrast. Each press of the UP or DOWN cursor key will change the contrast by a step in that direction. Adjust the contrast for best viewing.

• Press any other key to exit the contrast-setting mode.

6.5 The Keypad does not r e s pond (LCD shows KEY S LOC K ED )

The keypad can be unlocked by holding the zero (0) key for 3 seconds. At this time the backlight will turn on and the display will return to normal mode. The keypad can again be locked by holding the zero key for 3 seconds until the display shows KEYS LOCKED.

6.6 The Keypad does not respond after silencing an Al arm, Warning or Trouble.

LCD continues to show the alarm, warning or trouble message. It is possible that the horn or strobe have been configured to respond in alarm, warning or trouble conditions, even though there is no horn or strobe connected (or perhaps they are used for some purpose that is not audible or visible). First, hold the HUSH key for five seconds, or until the display changes to “ALARM silenced for 5 minutes” or another relevant message. Second, use the configuration menu to disable the horn or strobe, if they are not being used for some other purpose.

6.7 After a power failure

After any power failure, the user should check the system clock. While system parameters are maintained in memory, the system clock is backed-up by a limited-capacity button cell battery.

6.8 MRS-485 Modbus Application

6.8.1 Normal Operation

1. When the LED is solid GREEN, the operation is normal, the MRS-485 knows the detector type, no errors are detected, and no MODBUS data are being received or transmitted over the RS-485 line.

2. When the LED is GREEN with random bursts of AMBER, the operation is normal and now data are being received or transmitted over the RS-485 line. The AMBER LED will come on anytime that there is data traffic.

6.8.2 Unknown Sensor Code

GREEN/OFF Alternating every 500 milliseconds - The MRS-485 doesn’t know the detector type, no MODBUS communication is in progress and no errors are detected.

To correct this condition:

1. Disconnect the power line from the MRS-485.

2. Disconnect the MODBUS line from the MRS-485.

3. Re-connect the Modbus Line to the MRS-485.

4. Re-connect the power line to the MRS-485.

6.8.3 Error Codes

Solid RED - The MRS-485 detected an error and no MODBUS communications are in progress. RED with random bursts of AMBER - The MRS-485 detected an error and AMBER is displayed when data are received or transmitted over the RS-485 line.

There are a number of conditions which are signalized in this way:

1. Current EEPROM Settings not initialized

2. Current EEPROM Settings have a bad checksum

3. Factory EEPROM Settings not initialized

4. Factory EEPROM Settings have a bad checksum

5. Unknown Sensor exponent value

6. Watchdog Reset

7. Loaded Factory EEPROM Settings in EEPROM Current Settings

8. Latched sensor type different than registered sensor type

9. Unknown sensor type because registration failed

6.8.4 Dip Switch Settings Codes

RED/GREEN Alternating every 200 milliseconds indicates that MRS-485 is in programming mode and waiting for the user to enter

new settings using the 8 switches.

RED/OFF Alternating every 200 milliseconds indicates that saving new settings failed. GREEN/OFF Alternating every 200 milliseconds indicates that saving new settings passed. RED/OFF Alternating every 500 milliseconds indicates that selected MODBUS address is not an accepted value.

4. Press following keys in the keypad to test corresponding functionality .

Table 7-1 Keypad keys for Testing Functionality

5. If all test is complete, turn off the DVP-120 or DVP-120B. Move the jumper back to bottom two pins of EXT connector for DVP120 and right two pins of J10 for DVP-120B.

6. Turn ON DVP-120 or DVP-120B and verify the normal operation as explained in section 4.1 Initial Operating Mode

7.2 Maintenance

DVP-120 and DVP-120B do not have parts that require regular maintenance. For fuse, replacement see Section 4.3 of the manual. In the event of trouble or any kind of help and support contact Macurco Technical Support 1-844-325-3050

8 Appendix A – Quick Setup

IMPORTANT: To properly and effectively program the system you must configure the Sensors, Relays, Zones, and Signals. If the user has not entered any parameters, the system WILL NOT be monitoring the sensors or controlling the ventilation system. The relays will be in the not actuated state and the horn and strobe outputs will be off. Be sure that the 4-20mA output on each sensor is set to “On”.

Configure System; allows the installer to set the time of day, the day of the week, load the default configuration, configure

custom sensors and change the password.

2. Configure Sensors; defines the Sensor type – CO, NO2, EX, NH3, H2S, REF, CO2, O2, Custom (wildcard) or None and sets Alarm Level, Warning Level, and Sensor Range

3. Configure Relays, Horn and Strobe: defines operation as Normally Off or On, Delay Time, Minimum Runtime – this applies to all three relays as well as the horn and strobe. Note: The Delay Time default is 1 minute. If the duration of a test procedure or gas exposure is less than 1 minute, the relays, horns, and strobes may not engage even though the DVP-120 display and the sensors respond. When testing the system disable the delay (set Delay Time to zero minutes/seconds).

Configure Zones: defines Sensor Input & Relay/Alarm Output and sets up the sensor Groups (set of sensors of the same

type and output within the same zone) - Sensor type, Sensor Number, Rising Trip point and Falling Trip point

5. Configure Signals: defines the output of the Alarm, Warning and Trouble Signals (Buzzer, Horn and Strobe) as On, Off, Intermittent, Continuous, etc.

Note 1: The default Password is 1234. If the password has been changed and/or lost:

o Power down the unit. Remove the Jumper Shorting Connector from the EXT header and place it on the top two pins

of the SYS header.

o Power up the DVP-120. The first display is the current password on the unit. o Power down the unit. Remove the Jumper Shorting Connector from the SYS header and place it back onto the two

bottom pins of the EXT header.

Note 2: When entering multiple digit values the Up arrow (  ) acts as an enter key and it is not necessary to enter all allowed fields. Any other key is ignored or cancels the current parameter change.

Note 3: The MENU key will cause the system to shift to the Configuration Menu. The up and down and left and right arrow keys will scroll through all configuration parameters.

The MENU key is also used to return to a higher-level menu, exit the configuration menus and finally return to normal mode.

Figure A-3 Keypad Layout

When exiting from the menu system to normal mode, if any configuration changes have been made, the panel will ask whether changes are to be saved.

Figure A-4 Save Configuration? Prompt

Pressing the zero (0) key at this point will cancel all changes except time and day of the week. Pressing the one (1) key will save all changes to memory, and the changes will then become immediately effective in controlling the ventilation system.

The numeric keys are used to change the particular parameter displayed. The underlined numeral, or space, on each display, indicates what will be changed by the numeric keys. The left and right arrow keys will enter the particular submenu and scroll through the items of the same type where appropriate, (e.g., enter the Configure Sensors submenu) and scroll through the parameter lists for the existing sensors. The up arrow key scrolls through the menu entries in the order listed here, while the down arrow key scrolls in the reverse order.

Changing the configuration parameters requires the entry of a password before changes can be made. The default password is 1234. In many cases, the parameter is entered as a string of numerals, but some parameters are selected by pressing a single key, e.g.

pressing 1 selects Monday, 2 selects Tuesday, etc.

↑ Average or Voting Mode

Figure A-26 Sensor Mode Selection → Configure Group 2 - repeat for up to three groups When multiple sensors are being monitored as a Group, the DVP-120 output can be based on either sensor Voting (default) or the

Average of all sensor readings in the Group. When the configuration is Average, the gas concentrations from all sensors in the Group are averaged.

• If the average is greater than or equal to the rising trip point, the zone outputs are activated.

• If the average is less than or equal to the falling trip point, the zone output(s) is de-activated.

• If the average is between the two trip points, the outputs remain in their previous state.

When the configuration is Voting, the number of sensors in the Group indicating a value greater than or equal to the rising trip point is counted.

• If the count is greater than or equal to t he Quorum (t he minim um number of sensor vot es in a Group nee ded) then t he zon e output(s) are activated.

• If the count of sensors indicating less than or equal to the falling trip point is greater than or equal to the Quorum the zone output(s) is de-activated.

• If a group has an equal number of sensors with gas readings greater than or equal the rising trip point and sensors with

readings less than or equal to the falling trip point, activating the output(s) is given priority.

It is up to the installer to ensure that the Quorum entry is appropriate for the configuration. Valid entries are from one to twelve, but a value greater than the number of sensor s being monitor ed b y the gro up stop s the gr oup fr om contr olling t he output s. The default Quoru m value is 1; in this case, only 1 sensor vote is needed to control the output.
