Section 1

GENERAL

Monroe Electronics’ Multi-Point Fieldmeter and Alarm System, Model 177A measures electrostatic fields (potential gradient) in terms of voltage per unit distance. Using probe-to-surface separation as a calibration factor enables use of this instrument for measurement of surface voltage as well.

As with other models of Monroe Electronics’ electrostatic fieldmeters, the Model 177A’s primary application is measurement and monitoring of electrostatic charge accumulation. As a charge increases on the surface of a material, the electrostatic field in the vicinity increases proportionately. The Model 177A Multi-Point Fieldmeter and Alarm System produces a reliable output signal directly proportional to the surface charge accumulation while making NO PHYSICAL CONTACT with the material being monitored.

The Monroe Electronics Model 177A is an intrinsically safe system, using FM-listed Monroe Electronics Model 1036 sensors, which continuously monitor the critical points in your facility to detect and warn of electrostatic charge buildup before it becomes a problem. In a typical alarmactivated or PLC-connected setup, as static levels in your application surpass a preset value, beyond which there may be a danger to personnel or possible disruption or destruction to the process or product, an initial warning is triggered and the process is allowed to continue. If the problem is rectified, the “warning” returns to a “normal” state. If the condition persists and the static level exceeds a second, more crucial value, an alarm is activated. This second-level alarm can be used to shut down the process until it is brought under control, or to further warn the operator of the more serious condition.

Each Model 177A will monitor up to four locations using Monroe Model 1036 sensors placed at distances up to 1000 feet from the instrument. Processes can be continuously monitored and recorder outputs may be utilized for long term, drift free data acquisition. Cascading of up to 32 units via RS485 permits monitoring of up to 128 sensor locations using a PC and the supplied software.

Factory Mutual Research Corp. approves the Model 1036 probes for use in Class I, Division 1, Groups C and D hazardous locations. To comply, approved intrinsic safety (IS) barriers must be used with the Model 1036. Reference FM Standard Class Number 3610:January 2000

This document provides the user, for hazardous and non-hazardous areas, with operational instructions for Monroe Model 1036 sensors and the corresponding Model 177A Fieldmeter/Alarm System.

ELECTRIC FIELDS AND FIELDMETERS

Electric Field

An electric field is a region in space characterized by the existence of an electric force (F) generated by an electric charge (q). The electric force F acting on a charge q in an electric field is proportional to the charge itself. The relationship of these quantities is expressed by the electrostatic force law [1]:

F = qE

E is called the electric field strength and is determined by the magnitude and locations of the other charges acting upon charge q

E = F/q

The electric field strength, E, is usually displayed in the unit of volt/meter (V/m), volt/centimeter (V/cm) or volt/inch (V/in).

Electric Fieldmeters

Charge is often difficult or impossible to measure directly. We rely on detection and measurement of the electric field from the charged object to determine the existence of the charged and to estimate the relative magnitude of the charge. The electrostatic fieldmeter is the instrument that measures electric field strength.

Electric field strength measurements can be difficult to measure and interpret correctly because of several factors that can affect the electric field itself or affect the measurement of the electric field. Guidance is given in this document to help understand or minimize the effects of these factors, and to otherwise correctly interpret electric field measurements.

Fieldmeters measure the electrostatic field (voltage per unit distance) at the aperture of a grounded probe. Ideally, a uniform electric field is established between a charged surface and a grounded surface. The grounded surface may be the grounded surface of the fieldmeter probe, or the fieldmeter probe may also be placed in the plane of a grounded surface (better). The electric field is set up between the grounded surface and the charged surface some distance, D, away. Fieldmeters are calibrated at a particular distance, such as V/inch or V/cm. Therefore, using the manufacturer’s calibrated distance (one inch or one centimeter) makes the measurement easier to interpret. Probeto-surface separation should be carefully controlled for accurate measurement.

Probe

Charged

Figure 1: Probe-to-Charged-Surface Separation, D

Monroe Electronics electrostatic fieldmeters use a feedback-driven, null seeking design to assure accurate, drift-free, non-contacting measurements. Accuracy is typically a moderate 3% in a carefully controlled geometry.

Figure 2 illustrates a Monroe Model 1036 fieldmeter probe in simple graphical form. This particular fieldmeter is a chopper-stabilized design that operates reliably in both ionized and non-ionized environments (refer to Appendix II.)

Surface

Figure 2: Monroe Model 1036 Fieldmeter Probe

Electrostatic fieldmeters measure electric field strength by non-contacting means. All the charged objects, voltage sources, and grounded conductors (including the fieldmeter probe housing) in the general area affect the electric field strength measurement. The fieldmeter measures the electric field strength only at its aperture. It does not have a viewing angle and it does not see the web or object directly in front of it as a separate entity. This can be demonstrated by measuring the electric field of an insulating sheet with a hole in it.

The measured field strength in (b) will be less than in ( a), but it won’t be zero.

Probe Hole

Figure 3: Insulating Sheet Electric Field Demo, Top View

The field over the hole will not be zero, even though there is no charge directly in front of the probe head. This is because the electric field at the probe aperture is a function of each charge on the sheet, and is also a function of the concentration of field due to the grounded probe itself.

Effect of Probe Type on Fieldmeter Readings

For measurement of insulating web surfaces, it is best to maintain the same distance from the fieldmeter to the web as when the fieldmeter was calibrated. Since most fieldmeters are calibrated at one inch, their apertures should be positioned one inch from the web. The Model 1036E probe will give accurate readings (as-is) at a measurement distance of one inch because its large grounded face helps to create a uniform electric field near the aperture of the probe. The Model 1036F probe is significantly smaller than the Model 1036E probe. Unless a grounded shroud is used to enlarge the smaller ground plane of the 1036F probe, the fieldmeter readings will be about 12% high because the electric field will converge on the small probe.

INSTALLATION

The Model 177A Multi-Point Fieldmeter and Alarm System, is designed to occupy a 1¾” space in a standard 19” equipment rack. A minimum of 4” should be left behind the instrument to allow for cable connections to the back panel.

For use in conjunction with central data collection and/or monitoring, the 177A may be placed at any convenient, centralized location provided that the distance to any one probe does not exceed 1000 feet. The probes should be placed at any location requiring the monitoring of charge buildup.

An earth ground is necessary for proper operation. The chassis of the instrument may be grounded through the line cord, but the chassis must be grounded. A three wire grounded line cord is provided with the unit. The power line connector is located on the rear of the instrument.

Probe Inputs:

Four probe-input connectors are located on the instrument back panel. These are 9-pin subminiature D female receptacles for mating to plugs on either the cables attached directly to the probes or extension cables or adapter cables used with them. Two captive screws normally furnished with the plugs may be secured to female thread inserts alongside each receptacle.

At least one probe must be connected for the 177A to operate.

Probes of different full scale sensitivities are available for use with the 177A. Each probe is marked with a number stamped on the gradient cap to indicate its sensitivity (see Table 1). As a default, each 177A is shipped with its firmware set to indicate 10KV full-scale. If the installation is using probes other than 10KV full-scale, the 177A will need to be re-set for a different full-scale value. To do this, reference the 177A Front Panel Programming Tree shipped with the unit. Place the 177A in Set-up mode and then navigate to the PT (Probe Type) block as shown in the tree. Change the probe type value stored to match the full-scale sensitivity of the probe being installed on that channel. Store the value and then exit the set-up mode.

Outputs:

Two types of outputs are available on the back panel to represent the inputs. Voltage outputs may be taken at four BNC connectors or 4-20 mA current outputs at screw terminals at JP2. Simultaneous 4channel 4-20 mA current output is optional.

The two possible voltage outputs are: [1] ±10 volts, [2] 0 – 5 volts (±2.5 volts full scale).

The positive 4-20mA loop outputs are at terminals 2, 4, 6 and 8 of JP2 for Channels 1-4, respectively. The returns are at terminals 1, 3, 5 and 7, which are connected to common. The unit provides a 12V nominal supply which gives a compliance range of 7 volts. An external supply may be connected which will be used by all 4 channels. The external supply must be less than 25 volts. Output compliance is external supply minus 5 volts. Note that this supply will be referenced to chassis and Analog ground. These outputs are in addition to the four voltage outputs. See the overview of the 4-20mA module in Section 11 on page 30 for more information.

NOTE: The wire color code for the line cord provided is:

HIGH SIDE OF LINE — BLACK or BROWN LOW SIDE OF LINE — WHITE or LIGHT BLUE SAFETY GROUND — GREEN or GREEN/YELLOW

Figure 7: Rear panel relay hookups

Rear panel alarm relay connections:

Three status LEDs and relays are assigned to each channel. These LEDs and relays are referenced as OK, WARNING, and ALARM. External monitoring equipment can be connected to these relays and indicator LEDs via screw terminals located on the rear panel of the instrument and assigned as specified on the instruments cover.

Connections should be made using the following diagram as a guide. For operational information refer to the Rear Panel Relay Connection segment in Section 8 of this manual.

PRINCIPLE OF OPERATION

Refer to Figure 9 for the following discussion.

The probe is placed to “view” the target surface, which is assumed to be charged. In this instance, the gradient cap containing the aperture faces the target surface.

A sensitive electrode behind the aperture is vibrated perpendicular to the electric field by means of a drive coil (vibrated toward and away from the target surface). An A.C. signal is induced onto the sensitive electrode due to the motion of the vibrating electrode in the electric field, which is created by the charges on the target surface. The modulation amplitude of the A.C. signal, relative to the drive coil signal, is related to the polarity of the charge on the target surface.

This A.C. signal, conditioned by a preamplifier, filter, and signal amplifier, is fed into a phasesensitive demodulator. This signal from this demodulator feeds an integrating amplifier. A fraction of the integrator’s output signal is fed back to the sensing electrode to null the signal from the external electric field.

The voltage signal from the integrator is thus directly proportional to the field intensity at the sensing electrode of the probe. The output signal from the integrator drives a meter for direct readout.

Using 1036E and 1036F Sensors

General

Models 1036E and 1036F electrostatic fieldmeter probes are electrically identical and interchangeable. The major differences are physical. Model 1036F is a small (1.75” dia. x 1.25” H), lightweight version for general-purpose applications, or where available space is a problem. Model 1036E, for most industrial applications, is a 1036F probe built into a standard Crouse-Hinds ½”-FS1 electrical box with a stainless steel cover.

Both probes utilize the same vibrating capacitor modulator, and both have built-in provisions for purging with filtered air to prevent contamination and long-term drift. Inert gas may also be used for purging in hazardous areas where the probe will be used in an inert gas atmosphere. Purge gas flow in the Model 1036F exits through the sensitive aperture only. Gas flow in Model 1036E is directed across the face of the probe as well as through the sensitive aperture. Both probes are designed to be used with Monroe Electronics Model 177A Static Monitor 4 Channel Electrostatic Fieldmeter/Alarm System.

Static electricity is a natural occurrence resulting from common converting, laminating, and printing applications. At times static electricity is little more than an annoyance. However, in applications where significant electrostatic charges accumulate, the effects can be very serious. Typical probe applications include static level safety monitoring in explosive environments and static level quality monitoring in sensitive machine areas.

1. Parts of the Models 1036E and 1036EH Fieldmeter probe enclosures are constructed from plastic. To prevent the risk of electrostatic sparking the plastic surface shall only be cleaned with a damp cloth.

2. The Models 1036E, 1036EH, 1036F & 1036FH Fieldmeter Probe enclosure contains aluminum and is considered to present potential risk if ignition by impact or friction. Care must be taken into account during installation and use to prevent impact or friction.

Installation

Sensitivity:

Full-scale sensitivity for any properly standardized and calibrated probe/instrument combination is dependent upon the gradient cap (containing the aperture) on each probe. Full-scale sensitivity for any given system or channel (in the case of a multi-channel system such as the Model 177A) can be determined by inspecting the gradient cap on the probe. Each gradient cap is stamped on its face with a number, which represents a different size aperture. This number relates to the sensitivity of the probe as shown in the table below. Probes are standardized at the factory in a uniform electric field between two relatively large metal plates (see Figure 12). Once standardized in this manner, they may be interchanged at will.

Probe Model Full Scale Sensitivity 1036_-3 ±1 kV/cm (±100 kV/M) 1036_-4 ±10 kV/cm (±1 MV/M) 1036_-5 ±20 kV/cm (±2 MV/M) 1036_-6 ±10 kV/in Standard 1036_-7 ±1 kV/in

Table 1: Probe Model vs. Full Scale Sensitivity

Mounting:

Probe mounting requirements for electrostatic field determinations will vary somewhat with the nature of the desired measurement. In general, it is best to mount the probe as near as practical to the surface being monitored, as long as the input signal remains less than the full-scale sensitivity of the probe. For example, mount the metric unit reading probes from Table 1 at one centimeter and the English unit reading probes at one inch, if feasible. It is strongly recommended that, where possible, the probe be mounted "looking" downward in order to minimize the probability of contaminants entering the aperture in the face.

Model 1036E is provided with two mounting flanges. The case should be electrically connected to ground. The gradient cap (containing the aperture) of the probe is a reference surface with its own ground connection. Do not make a separate ground connection to this surface. Stainless steel hardware is recommended as shown for this connection to avoid long-term corrosion issues.

Model 1036F may be held by hand to make rough measurements, or mounted by means of two threaded inserts installed in the mounting block. Care must be exercised when selecting screw length. Other temporary mounting options are friction clamps, adhesives or double-sided tape. The metal body of the probe is internally connected to instrument ground and should not normally be connected to any other ground.

Geometry:

A shroud is not necessary on 1036E probes mounted at 1in/1cm or less from the web because the large faceplate provides the same function as a shroud (creates a uniform field in front of the probe at one inch or less).

As a truly uniform field does not usually occur in most practical measurement situations using the 1036F probes, partly due to the introduction of the grounded probe itself, one must either:

 Improve the geometry by establishing a grounded plane (shroud) through which the fieldmeter

probe can view the field under consideration. Refer to figure 6 on page 9. (see also Application Note –0003 in Appendix.)

 Establish a correction factor for the data, or  Accept relative data. In many cases, this is acceptable practice once a fixed geometry is

established and related to the real electric field.

Cables:

Both types of probes are normally equipped with 10-foot-long cables and subminiature D connectors that mate with Monroe Electronics Model 177A. This is Option 1 of 6 available wiring options – see Appendix A – Probe Connection Options for details. The first 3 options are for non-hazardous (nonclassified) locations where there are no Intrinsic Safety (IS) considerations. The last 3 options are for hazardous (classified) locations where IS must be considered as part of the installation and barriers are in use.

Extension cables are available from Monroe in lengths up to 1000 feet, which is the maximum permissible length. These extension cables may be ordered in any length (up to 1000 feet) by part number 1036/12-nnnn, where nnnn is the length in feet.

The cable exit on Model 1036E is supplied through a packing gland which is screwed into a ½"-14 NPT tapped hole in a boss on one end of the housing. Inside the housing, the probe is plugged into a terminal block to which the cable attaches. Where it is desirable or necessary to connect Model 1036E probes to Model 177 Static Monitors with conduit, the original cable and packing gland can be removed and the cable replaced by any length (up to 1000 feet) pulled through the conduit with a connector on only the Model 177 end. Refer to Appendix A – Probe Connection Options, Options 3, 4 or 6 (depending on whether IS must be considered) for details.

Purging:

Any "contamination" present in the probe or near the measurement will have an adverse affect on performance. When insulative particles or liquid becomes charged and enters the probe or attaches near the aperture of the probe, it becomes a source of measurement error and drift. Less obvious is the influence of gaseous atmospheric constituents, including aerosols, which contaminate the probe by altering the contact potentials between critical surfaces.

Constant purging of the Model 1036 probe with clean dry air or an inert gas is recommended whenever practical to prevent airborne contaminants from entering the aperture in the gradient cap and being deposited on the electrode.

The air supply should meet standard ANSI/ISA-S7.0.01-1996 - Quality Standard for Instrument Air. A Koby "Junior" filter available from Koby, Inc., 297 Lincoln Street, Marlboro, MA 01752 should meet this standard and will provide sufficient mechanical and chemical filtration for one to four probes under most conditions.

A complete probe purge kit, Model 1017/22G, is available for Model 1036F from Monroe Electronics. It includes a low volume, long-life air pump, mechanical and chemical filters, and a supply of tubing. The pump is fully capable of 24-hour per day operation, thus keeping the probe ready for immediate use. A purge gas inlet tube supplied with each 1036F probe may be installed in either of two positions, the choice of which is primarily a matter of convenience in routing of the hose carrying the purge gas. These consist of tapped holes that exit at 90° to each other near the probe cable. If it is desired to move the purge tube to the other location, simply switch it with the Allen set screw plugging the other hole.

Purge the Model 1036E probe through a ¼"-18 NPT tapped hole in the end of the housing near the cable exit using common plumbing or tubing components.

Gas pressure to either probe type should be sufficient to produce a slight positive flow out of the probe and in no event should exceed a pressure of ½ psi.

Servicing

General:

It must be emphasized that the critical elements of these probes (gradient cap and sensing electrode) must be kept free from contaminants, e.g., dust, fumes, mists or any foreign material. The materials of which these probe elements are made were very carefully chosen to minimize contact potential. Any foreign matter which will cause relative electrical activity when combined with relative motion will tend to cause drift and measurement errors.

Therefore, it is recommended that:

 Probes be constantly purged even when not in use, if this is practical.  Probes be kept tightly covered when not in use and are not being purged to prevent

contamination. A covering such as a plastic bag or aluminum foil may be used. DO NOT cover the sensitive aperture with adhesive tape.

 Probes be cleaned only to the degree and frequency necessary to achieve the required

stability.

 Gradient caps NOT be removed for cleaning unless absolutely essential.  Major cleaning and reconditioning be should performed by the factory.

Cleaning:

The recommended cleaning solvent is instrument grade 70-100% isopropyl alcohol applied with a suitable soft, lint-free applicator. Use of a non-approved solvent may degrade performance permanently, requiring factory service.

Outside surfaces of the probe should first be wiped clean with a lint-free wiping tissue saturated in solvent. Then the interior surfaces should be flushed with solvent, using a plastic squeeze bottle through the aperture until no dirt or dust may be seen. The probe should then be allowed to drain and dry thoroughly. A 15-minute bake-out at 75°C is recommended to remove residual solvent.

Disassembly/Assembly, Model 1036E:

In order to rewire the cable terminal block, replace or standardize the probe assembly and, in most cases, to calibrate Model 1036E, it must first be removed from its housing. This is done by loosening the four cross point screws around the outer edge of the cover 1-1½ turns each, in turn, several times while lifting the cover and probe straight out of the housing until it is completely removed. DO NOT attempt to remove the screws completely one at a time. These four screws have circular

"E-rings" installed on them under the cover plate to make the screws captive and prevent their falling into machinery below. The probe assembly will need to be removed from the cover plate, for standardizing, calibration, or to replace the gradient cap. This is done by removing the four cross point screws which secure the phenolic mounting block to the hex standoffs, leaving the standoffs attached to the cover plate.

To reassemble the probe unit, reverse the above procedure. After the phenolic mounting block has been re-secured to the four hex standoffs, the probe unit should be inspected to assure that an even air gap exists completely around the gradient cap between the cap and the cover plate. If not, loosen the two cross point screws which secure the probe body to the phenolic mounting block, and adjust the probe body so that it is centered and completely surrounded by an even air gap.

Partially mate the card-edge fingers into the terminal block connector in the housing and tighten the four outer screws in the cover plate 1-1½ turns at a time until the assembly is secured in the housing.

Standardization:

A simple accurate means of standardizing Model 1036 probes using any channel of the Model 177A Static Monitor as a test vehicle is given here.

The primary reason for standardization of type 1036 probes is to assure interchangeability of probes. The procedure is not suggested as routine, but is presented here in the event it becomes necessary to re-standardize following replacement of a gradient cap or major probe overhaul. It should be performed only under controlled conditions in a suitably equipped electronics laboratory. Monroe Electronics recommends that all probe standardization be performed at its facility.

All type 1036 probes are shipped from the factory standardized in a uniform (parallel) electric field using a fixture similar to that shown in Figure 12. The fixture consists of two flat rigid metal plates, which are parallel and separated with insulators by a distance "d" of one inch and have side dimensions of at least 5d (the bigger, the better; within practical limitations). The ground plate has a hole in its center just large enough to provide clearance around the probe so that the probe does not make contact with the plate. A calibrating voltage is applied to the gradient plate to establish a reference field in the volume between the plates. This fixture is available from Monroe Electronics, Inc. as part number 96102A.

The standardization procedure is as follows:

 Set up apparatus as outlined above. Set a precision calibrating voltage source to zero volts.  Set the Model 177A Static Monitor zero control of the selected channel to read a value of

0.000 at its ±10V analog output using a high quality, 4½ digit digital multimeter (DMM).

 Apply calibrating source voltage (VHV) shown in Table 2 for the probe model being

standardized.

 Adjust the standardization potentiometer in the probe to produce value (V

), as shown in

IND

Table 2, at the analog output of the selected channel using the same DMM as above.

OPERATION

Console Switches

Figure 15: Front Panel View

PWR – Switches unit ON or OFF (There is a main power switch on the rear panel that supplies DC power. The front panel console push button switches the power to the to the unit’s power supply.) If line power is lost, the 177A will return to operational status when power is restored.

GROUP ENA/DIS - All channels in the group (of four) are enabled on power-up. These channels may be immediately and simultaneously disabled by pressing the GROUP ENA/DIS button on the front panel or clicking the GROUP ENA/DIS button on the program monitor screen.

SETUP – Initiates programming via the front panel. Yellow Program LED lights when SETUP button is pressed and remains lit for duration that instrument is in program mode.

TEST – Initiates testing of all connected and enabled probes. Pressing and holding down the TEST button causes a shift in the probe reading to the minus direction, the reading should return to normal when the button is released, indicating a good probe.

ENTER – Press ENTER to accept changes during programming or to perform a function.

EXIT – Press EXIT to escape the changes or exit the program mode.

Console LEDs

POWER – Green LED lights when power is applied to the instrument. A flashing power LED

indicates a problem with the instrument’s power supplies. If this occurs refer to the Return Policy on page 3 for servicing.

PROGRAM – Yellow LED lights when the SETUP switch is depressed and remains lit until the

program mode is exited. If master/slave units are utilized the program light will pulse on the master unit which drives probe oscillation. If it is a slave unit the program light will not be lit.

The program LED does not pulse when the unit is in program mode.

The program light flashes (pulses at a slower rate) when the unit is receiving a firmware update. If the update is interrupted either, by the user or power failure, the light will flash and remain flashing until the update is completed successfully.

FP LOCK – Red LED indicates that the front panels controls have been locked. When locked the

front panel buttons do not function except for Power, Setup and Exit. FP lock can be enabled or disabled via the front panel controls or the pc software supplied.

REMOTE – Lights when the PC program is in use.

Rear Panel Relay Connections

Three status LEDs and relays are assigned to each channel. These LEDs and relays are referenced as OK, WARNING, and ALARM. External monitoring equipment can be connected to these via screw terminals located on the rear panel of the instrument. Connections are specified in Figure 7 on page 10 and on the instrument’s cover.

Three modes of operation are available:

Alarm Mode - Latching

Under normal operating conditions (i.e. the monitored static level is less than the preset warning and alarm levels) all three relays are energized initiating a contact closure. The green or OK status LED is blinking while the yellow or WARNING and red or ALARM status LEDs are not lit.

When static levels reach the preset Warning level and the preset Alarm Delay has expired (refer to Program Setup in Section 9 for details) the Warning relay will open and the Warning LED will light. The OK LED will continue to blink. Whenever the instrument achieves Warning mode it will stay in that condition until the problem is corrected or the static level falls to less than the preset warning.

When static levels reach the preset Alarm level and the preset Alarm Delay has expired (refer to Program Setup in Section 9 for details) the Alarm relay will open and the Alarm LED will light. The OK LED will continue to blink and the Warning LED remains lit as well.

System Alarm - Upon realization of an alarm condition the System Alarm relay will open. Upon opening the System button on the Monitor screen on your pc will flash red.

Whenever the instrument achieves Alarm mode it will stay in that condition until the problem is corrected and the instrument is manually reset by toggling the channel’s ENA/DIS button on the instrument console or via the pc program provided or by momentarily shorting the Alarm Reset terminals on the back panel.

Alarm Mode – Non-Latching

System Alarm - Upon realization of an alarm condition the System Alarm relay will open. Upon opening the System button on the Monitor screen on your pc will flash red.

Whenever the instrument achieves Alarm mode it will stay it that condition until the static level falls to less than the preset warning level resetting to normal operation.

Non-Alarm Mode

In non-alarm mode the alarms are disabled, the green or OK remains lit continuously. Warning and Alarm are not triggered. The instrument continues to monitor static levels regardless of operating conditions.

Channel Switches

ENA/DIS – Toggles the channel status between Disable / Enable / Alarm

ZERO – Press and release the ZERO button to zero the channel. Display will return to pre-set zero

level. The channel display to the immediate right of the channel display being zeroed will count down the pre-set zero time out. (For Channel 4 the channel display immediately to the left will count down the zero time out.) If zero level is reached within the pre-set time the channel display will read don for “done.” If the zero level is not reached within the pre-set time the display will read err for “error.”

Auto-Zero – Press and release the Zero button (< 1sec)

Manual Zero – Press and hold the zero button then push the up or down arrow buttons to

adjust the zero reading

Channel LEDs

Green (left) LED – Lights and remains lit when a probe is connected and the channel is enabled

(Non-Alarm mode). Lights and flashes when a probe is connected and the channel alarm is enabled. (Alram Mode: Latching and non-latching.) LED remains flashing even as the Yellow, Warning and Red, Alarm LEDs light during warning and alarm conditions.

Yellow (center) LED – Lights when the pre-set voltage warning level is reached. Remains lit until voltage level drops below warning level (non-latching) or until the condition corrected and the channel is reset (Latching).

Red (right) LED - Lights when the pre-set voltage alarm level is reached. Remains lit until voltage level drops below warning level (non-latching) or until the condition corrected and the channel is reset (Latching).

177A Relay and LED Functions

Initially all Ok, warning, alarm relays are closed (shorted or activated). The Ok LED is on; warning and alarm LEDs are off.

Channel Ok relay is open (the green LED off) when:

 The channel is enabled and has no probe.  The channel is disabled.

Channel Warning relay is open (the ember LED on) when: The channel is enabled and the reading is on or above the warning level.

Channel Alarm relay is open (the red LED on) when:

 The channel is enabled and has no probe.  The channel is enable and the reading is on or above the alarm level.

If the unit is in alarm latching mode and the reading comes back down, the relay will not close

until the [Ena/Dis] or [GRP] button is depressed.

System relay is normally closed. It is open when:

 One or more of the alarm relay is open.  One or more of the enabled channel has no probe.  Power supplies have failed.

Power LED: On when the unit is powered up. Slow blink if power supply has failed.

Program LED: Normally off. It is on when doing front panel setup. Pulses on when the unit is a master. See section on master/slave operation in the User Manual.Note: if USB cable A & B are connected to the same unit, oscillator is disabled.

FP Lock LED:

Normally off. On when the front panel is locked. When the front panel is locked, only the [Setup] and arrow buttons work. You can unlock the unit, or browse the program setup but cannot change it.

Master/Slave out & Slave in:

Purpose

These connections provide synchronization of the probe modulators on multiple 177A’s. When probes are attached to common mountings from multiple 177A’s they can interact and cause zero shifts and low frequency oscillations without synchronization of the modulators.

Setup

Master/Slave out and Slave in connectors are provided on each 177A. The Master/Slave out either generates or passes through reference signal for synchronization. Multiple units can be daisy chained as shown in Fig 14, on page 17.. The Slave in connector accepts the Reference and forces the modulator to be synchronized with the other 177A’s. Standard USB cables with Type A/B connectors are used for interconnects. These are supplied with the 177As.

Note. These connectors are NOT USB Ports

Remote LED

Normally off. Blinks when serial port is receiving.

Diagnostic

From the Monitor drop-down menu select Diagnostic, the following window will open:

Selecting this window from the MONITOR drop-down menu on the main screen permits reading and writing to the front panel displays, LEDs, and exercising the system relay contacts. Before using this feature, the 177A must be connected and set to Group-Disable to permit control of these items. This feature is helpful in testing all external relay contact wiring to external devices.

To turn an LED or relay contact on or off or to obtain it’s status, click on the appropriate box on the Set LED/Relay grid, then click the On, Off, or Read button. Remember that the relay contacts are set to be “fail safe” meaning that when conditions are O.K. in normal operation, these contacts are closed. They will then open under caution or alarm conditions or system failures. See Figure 8, on page 10, for examples of connecting external devices.

To read a register (channel display), select the channel in the Channel Display box in the right of the Diagnostic window, and then click the Read button. The selected channel display data is shown in the window below the channel display pull-down.

Numerical or text data can be written to any channel display by first selecting the channel in the Channel Display pull-down in the right of the Diagnostic window, entering the data to be written in the boxes below and then clicking the Write Number or Write Text button.

Display decimal points can be checked by using the Set Decimal box. Select the decimal position to be written and then click the Set Decimal button. The display should show the correct decimal point with associated zeros. This only checks the functionality of the decimal point and does not alter the setting used in the Edit Channel screen of the Program Setup.

Any settings written to the unit during diagnostic checks are automatically canceled when the unit is cycled back to Group Enable.

The Read / Write commands use MODBUS protocol. The addresses for the relays, LEDs, and displays are listed below and in the Coil Address Table in the help menu of the Read / Write Coils window.
