Introduction

VLT® Compressor Drives CDS 302/CDS 303

1 Introduction

1.1 Introduction

Figure 1.1 Compressor Drive System

The VLT

Compressor Drives utilize and combine Danfoss design and manufacturing expertise. Our extensive application knowledge of refrigeration, air conditioning, and motion controls ensures an optimized product design and package solution:

A “plug & play” solution

•

Operational eciency

•

Flexibility & best control accuracy

•

Innovative and reliable solution

•

The frequency converter is 100% preset for speed open loop conguration with 0-10 V reference corresponding to

1800-5400 RPM for CDS 302 and 1500-6000 RPM for CDS

303.

Introduction Operating Instructions

1 1

The dedicated frequency converter functionality includes:

Start Up

•

Once the frequency converter has a start command, the compressor runs up to 3000 RPM and remains at that speed for 10 s. Once this initial time is complete, the frequency converter slowly ramps to the reference speed.

Shut Down

•

The stop command bypasses the normal ramp time and the frequency converter ramps the compressor to stop fast.

Short Cycle Prevention

•

The frequency converter has a minimum running time of 12 s, with an interval between starts of 5 minutes (300 s). The short cycle delay values are adjustable in parameter group 28-0* Short Cycle Protection.

Oil Injection

•

The frequency converter cycles a solenoid valve via its relay 1. This cycling ensures that the oil is distributed to the scroll set, improves tightness, and reduces internal gas leakage during the compression process.

Oil Management

•

If compressor speed is below 3000 RPM for a determined amount of time (within 60 minutes), the boost cycle runs the compressor back to 4200 RPM for a determined amount of time (within 90 s). The maximum time between xed boosts is limited to a determined amount of time (within 24 hours).

Discharge Temperature Limit

•

If the discharge temperature exceeds the warning level of 266 °F, the compressor drops in speed by 10 Hz for the next 3 minutes. The compressor continues to drop 10 Hz for each 3 minutes for as long as the temperature is over the warning level. If the discharge temperature exceeds the emergency level of 293 °C, the compressor is stops.

Crankcase Heater

•

On VSH088 and VSH117, when the compressor is stopped, the frequency converter provides a DC current to the compressor motor. The DC current keeps the oil warm and an external crankcase heater is not needed. VSH170 needs an external crankcase heater (surface sump heater or belt type).

Low Pressure Switch

•

An LP switch is mandatory with the frequency converter compressor in any type of application.

High Pressure Switch

•

The high-pressure switch must be connected to input terminal 37 of the frequency converter in series with the other safety devices.

1.1.1 Sequence of Operation

All compressor types have strong demands of speed limits to ensure the oil lubrication of the bearings. Therefore, fast acceleration from standstill to minimum speed with a special start ramp is important, when a start command is given. This is also the reason why the Compressor Drive trips with an alarm [A49] Speed Limit, if the speed falls below minimum speed e.g. when the current limit controller reduces the speed due to a high load. This alarm is reset automatically after 30 s and the compressor restarts.

If a rotor is blocked, the Compressor Drive trips with an alarm [A18] Start failed, if the speed fails to get above the minimum speed limit for the compressor within 2 s. This alarm is reset automatically after 30 s and the compressor restarts.

The manufacturer sets up the necessary start settings, motor data and all the other preferred settings for each compressor type/size. Automatically set up the values by selecting the actual compressor in 1-13 Compressor Selection.

2.1.6 General Warning

WARNING

Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains. Also make sure that other voltage inputs have been disconnected, such as load-sharing (linkage of DC intermediate circuit).

Using VLT® Compressor Drives: Wait at least 15 minutes. Shorter time is allowed only if indicated on the nameplate for the specic unit.

2.1.7 Leakage Current

CAUTION

The ground leakage current from the frequency converter exceeds 3.5 mA. Ensure good mechanical ground connection (terminal 95) to the ground cable. Use at least 10 mm2 cable cross section or 2 times rated ground wires terminated separately.

2.1.8 Residual Current Device

CAUTION

This product can cause a DC current in the protective conductor. Where a ground fault interrupter (GFI) is used for extra protection, only use an GFI of Type B (time delayed) on the supply side of this product. See also RCD Application Note, MN90G. Protective grounding of the frequency converter and the use of RCDs must always follow local and national regulations.

2.1.9 IT Mains

CAUTION

Do not connect 400 V frequency converters with RFI- lters to mains supplies with a voltage between phase and ground of more than 440 V. For IT mains and delta ground (grounded leg), mains voltage may exceed 440 V between phase and ground. To disconnect the internal RFI capacitors from the RFI lter to ground, use 14-50 RFI 1 on the frequency converter. This procedure reduces the RFI performance to A2 level.

2.1.10 Avoid Unintended Start

While the frequency converter is connected to mains, the motor can be started/stopped using:

digital commands

•

bus commands

•

references

•

via the Local Control Panel (LCP)

•

Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unintended start. To avoid unintended start, always press [OFF] before changing parameters. An electronic fault, temporary overload, a fault in the mains supply, or lost motor connection may cause a stopped motor to start. A frequency converter with Safe Torque O provides a certain degree of protection against such unintended start, if the Safe Torque O Terminal 37 is on low voltage level or disconnected.

2.2 Safe Torque O

The frequency converter can perform the safety function

Safe Torque Stop Category 0 (as dened in EN 60204-12).

Before integration and use of Safe Torque O in an installation, perform a thorough risk analysis to determine whether the Safe Torque O functionality and safety levels are appropriate and sucient. Safe Torque O is designed and approved suitable for the requirements of:

•

Refer to EN IEC 61800-5-2 for details of Safe torque o

(STO) function.

Refer to EN IEC 60204-1 for details of stop category 0

and 1.

Activation and Termination of Safe Torque

The Safe Torque O (STO) function is activated by removing the voltage at terminal 37 of the safe inverter. By connecting the safe inverter to external safety devices providing a safe delay, an installation for a Safe Torque O Category 1 can be obtained. The Safe Torque O function can be used for asynchronous, synchronous, and permanent magnet motors.

2.2.1 Terminal 37 Safe Torque O Function

The frequency converter is available with Safe Torque O functionality via control terminal 37. Safe Torque O disables the control voltage of the power semiconductors of the frequency converter output stage. This in turn prevents generating the voltage required to rotate the motor. When the Safe Torque O (T37) is activated, the frequency converter issues an alarm, trips the unit, and coasts the motor to a stop. Manual restart is required. The Safe Torque O function can be used as an emergency stop for the frequency converter. In normal operating mode when Safe Torque O is not required, use the regular stop function instead. When automatic restart is used, ensure the requirements of ISO 12100-2 paragraph

5.3.2.5 are fullled.

Safe Torque O Installation and Set-Up

WARNING

SAFE TORQUE OFF FUNCTION!

The Safe Torque O function does NOT isolate mains voltage to the frequency converter or auxiliary circuits. Perform work on electrical parts of the frequency converter or the motor only after isolating the mains voltage supply and waiting the length of time specied in chapter 2.1 Safety and Warnings. Failure to isolate the mains voltage supply from the unit and waiting the time specied could result in death or serious injury.

It is not recommended to stop the frequency

•

converter by using the Safe Torque O function. If a running frequency converter is stopped by using the function, the unit trips and stops by coasting. If unacceptable or dangerous, use another stop mode to stop the frequency converter and machinery, before using this function. Depending on the application, a mechanical brake can be required.

For synchronous and permanent magnet motor

•

frequency converters, in a multiple IGBT power semiconductor failure: In spite of the activation of the Safe Torque produce an alignment torque which maximally rotates the motor shaft by 180/p degrees. p denotes the pole pair number.

This function is suitable for performing

•

mechanical work on the system or aected area of a machine only. It does not provide electrical safety. Do not use this function as a control for starting and/or stopping the frequency converter.

To perform a safe installation of the frequency converter, follow these steps:

1. Remove the jumper wire between control terminals 37 and 12 or 13. Cutting or breaking the jumper is not sucient to avoid shortcircuiting. (See jumper on Figure 2.2.)

2. Connect an external Safety monitoring relay via a NO safety function to terminal 37 (Safe Torque O) and either terminal 12 or 13 (24 V DC). Follow the instruction for the safety device. The Safety monitoring relay must comply with Category 3 /PL “d” (ISO 13849-1) or SIL 2 (EN

62061).

O. Moreover, perform the test after each modication of the installation.

Example with STO

A safety relay evaluates the E-Stop button signals and triggers an STO function on the frequency converter in the event of an activation of the E-Stop button (See Figure 2.4). This safety function corresponds to a category 0 stop (uncontrolled stop) in accordance with IEC 60204-1. If the function is triggered during operation, the motor runs down in an uncontrolled manner. The power to the motor is safely removed, so that no further movement is possible. It is not necessary to monitor plant at a standstill. If an external force eect can occur, provide additional measures to prevent any potential movement (for example mechanical brakes).

NOTICE!

Figure 2.2 Jumper between Terminal 12/13 (24 V) and 37

For all applications with Safe Torque O it is important that short circuit in the wiring to T37 can be excluded. Exclude the short circuit as described in EN ISO 13849-2 D4 by the use of protected wiring (shielded or segregated).

Safe Torque O Commissioning Test

After installation and before rst operation, perform a commissioning test of the installation using Safe Torque

Example with SS1

SS1 corresponds to a controlled stop, stop category 1 according to IEC 60204-1 (see Figure 2.5). When activating the safety function, the frequency converter performs a normal controlled stop. This can be activated through terminal 27. After the safe delay time has expired on the external safety module, the STO will be triggered and terminal 37 will be set low. Ramping down as congured in the frequency converter. If the frequency converter is not stopped after the safe delay time, the activation of STO will coast the frequency converter.

NOTICE!

When using the SS1 function, the brake ramp of the frequency converter is not monitored with respect to safety.

Example with Category 4/PL e application

Where the safety control system design requires two channels for the STO function to achieve Category 4/PL e, implement one channel via Safe Torque O T37 (STO) and the other by a contactor. Connect the contactor in either the frequency converter input or output power circuits and controlled by the Safety relay (see Figure 2.6). The contactor must be monitored through an auxiliary guided contact, and connected to the reset input of the Safety Relay.

Paralleling of Safe Torque O input the one Safety Relay

Safe Torque O inputs T37 (STO) may be connected directly if it is required to control multiple frequency converters from the same control line via one Safety Relay

(see Figure 2.7). Connecting inputs increases the probability of a fault in the unsafe direction. A fault in one frequency converter can result in all frequency converters becoming enabled. The probability of a fault for T37 is so low, that the resulting probability still meets the requirements for SIL2.

1. Activate the Safe Torque O function by

removing the 24 V DC voltage supply to the terminal 37.

2. After activation of Safe Torque O (that is, after the response time), the frequency converter coasts (stops creating a rotational eld in the motor). The response time is typically less than 10 ms.

The frequency converter is guaranteed not to restart creation of a rotational eld by an internal fault (in accordance with Cat. 3 of EN 954-1, PL d acc. EN ISO 13849-1 and SIL 2 acc. EN 62061). After activation of Safe Torque O, the display shows the text ”Safe Stop activated”. The associated help text says, "Safe Stop has been activated. This means that the Safe Torque O has been activated, or that normal operation has not been resumed yet after Safe Torque O activation”.

NOTICE!

The requirements of Cat. 3 (EN 954-1)/PL “d” (ISO 13849-1) are only fullled while 24 V DC supply to terminal 37 is kept removed or low by a safety device which itself fullls Cat. 3 (EN 954-1) PL “d” (ISO 13849-1). If external forces act on the motor, it must not operate without additional measures for fall protection. External forces can arise for example, in the event of vertical axis (suspended loads) where an unwanted movement, for example caused by gravity, could cause a hazard. Fall protection measures can be additional mechanical

brakes.

By default the Safe Torque O function is set to an Unintended Restart Prevention behaviour. Therefore, to resume operation after activation of Safe Torque O,

1. reapply 24 V DC voltage to terminal 37 (text Safe Torque O activated is still displayed)

2. create a reset signal (via bus, Digital I/O, or [Reset] key.

WARNING

Safe Torque O activation (that is removal of 24 V DC voltage supply to terminal 37) does not provide electrical safety. The Safe Torque O function itself is therefore not

Automatic Restart Behaviour is permitted in one of the two situations:

1. The Unintended Restart Prevention is implemented by other parts of the Safe Torque O installation.

2. A presence in the dangerous zone can be physically excluded when Safe Torque O is not activated. In particular, paragraph 5.3.2.5 of ISO 12100-2 2003 must be observed

2.2.2 Safe Torque O Commissioning Test

After installation and before rst operation, perform a commissioning test of an installation or application, using Safe Torque O. Perform the test again after each modication of the installation or application involving the Safe Torque O.

NOTICE!

A passed commissioning test is mandatory after rst installation and after each change to the safety installation.

The commissioning test (select one of cases 1 or 2 as applicable):

Case 1: Restart prevention for Safe Torque O is required (that is Safe Torque O only where parameter 5-19 Terminal 37 Safe Stop is set to default value [1], or combined Safe Torque O and MCB 112 where parameter 5-19 Terminal 37 Safe Stop is set to [6] PTC 1 & Relay A or [9] PTC 1 & Relay W/A):

1.1 Remove the 24 V DC voltage supply to terminal 37 using the interrupt device while the frequency converter drives the motor (that is mains supply is not interrupted). The test step is passed when

the motor reacts with a coast, and

NOTICE!

See warning on the restart behaviour in

chapter 2.2.1 Terminal 37 Safe Torque O Function

WARNING

The Safe Torque O function can be used for asynchronous, synchronous and permanent magnet motors. Two faults can occur in the power semiconductor of the frequency converter. When using synchronous or permanent magnet motors a residual rotation can result from the faults. The rotation can be calculated to Angle = 360/(Number of Poles). The application using synchronous or permanent magnet motors must take this residual rotation into consideration and ensure that it does not pose a safety risk. This situation is not relevant for asynchronous motors.

Screening of cables

Avoid installation with twisted screen ends (pigtails). They reduce the screening eect at higher frequencies.

Cable length and cross section

The frequency converter has been tested with a given length of cable and a given cross section of that cable. If the cross section is increased, the cable capacitance - and thus the leakage current - may increase, and the cable length must be reduced correspondingly.

Aluminum conductors Aluminium conductors are not recommended. Terminals accept aluminium conductors, but clean the conductor surface and remove and seal the oxidation by neutral acidfree Vaseline grease before the conductor is connected. Furthermore, the terminal screw must be retightened after two days due to the softness of the aluminium. It is crucial to keep the connection a gas tight joint, otherwise the aluminium surface oxidizes again.

Use terminal 37 as input for safe stop. In rare cases, control cables more than 100 m (330 ft) and analog signals result in 50/60 Hz ground loops due to noise from mains supply cables. If this situation occurs, break the screen or insert a 100 nF

capacitor between screen and chassis. Connect the digital and analog inputs and outputs separately to the frequency converter common inputs (terminal 20, 55, 39) to avoid ground currents aecting the system.

e. Cables for serial communication

Eliminate low-frequency noise currents between two frequency converters by connecting one end of the screen to terminal 61. This terminal is connected to ground via an internal RC link. To reduce the dierential mode interference between the conductors, use twisted-pair cables.

b. Wrong grounding

Do not use twisted cable ends (pigtails). They increase the screen impedance at high frequencies.

c. Protection concerning ground potential between PLC (Program Logic Controller) and frequency converter

If the ground potential between the frequency converter and the PLC (etc.) is dierent, electric noise may occur that disturbs the entire system. Solve this problem by tting an equalizing cable, next to the control cable. Minimum cable cross-section: 16 mm2.

d. For 50/60 Hz ground loops

If long control cables are used, 50/60 Hz ground loops may occur. Solve this problem by connecting one end of the screen to ground via a 100 nF capacitor (keeping leads short).

3.3.12 Electrical Installation - EMC Protection

The following is a guideline to good engineering practice

when installing frequency converters. To comply with EN 61800-3 First environment, follow these guidelines. If the installation is in EN 61800-3 Second environment, i.e. industrial networks, or in an installation with its own transformer, deviation from these guidelines is allowed, but not recommended.

Good engineering practice to ensure EMC-correct electrical installation

Use only braided screened/armored motor

•

compressor cables and braided screened/armored control cables. The screen should provide a minimum coverage of 80%. The screen material must be metal, not limited to but typically copper, aluminum, steel, or lead. There are no special requirements for the mains cable.

Installations using rigid metal conduits are not

•

required to use screened cable, but the motor compressor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the frequency converter to the motor compressor is required. The EMC performance of exible conduits varies a lot and information from the manufacturer must be obtained.

Leave the screen as close to the connectors as possible.

Figure 3.27 shows an example of an EMC-correct electrical installation of an IP20 frequency converter. The frequency converter is tted in an installation cabinet with an output contactor and connected to a PLC, which is installed in a separate cabinet. Other ways of doing the installation may have just as good an EMC performance, provided the above guide lines to engineering practice are followed. Installing without following the guideline, and using unscreened cables and control wires do not comply with all emission requirements, although the immunity requirements are

RELAY 2

RELAY from MCB 105

130BD448.10

How to Install Operating Instructions

The BASIC Cascade/Pack Controller is used for up to 3 compressors to control up to two on/o compressors together with one variable speed compressor. The capacity control is typically based on suction pressure feedback, but it could also be e.g. a cold room temperature.

Fixed Lead Compressor

The BASIC Pack Controller allows the frequency converter to control up to 3 compressors using the frequency converter's two built-in relays. The variable compressor (lead) is connected directly to the frequency converter, while 2 bilt-in relays control the other 2 compressors.

NOTICE!

Only one xed speed compressor can be controlled with the built-in relays. To control two xed compressors, an extra relay is needed via the MCB 105 Relay Option.

Bandwidth Management

In pack control systems, to avoid frequent switching of xed speed compressors, the desired system load is kept within a bandwidth rather than at a constant level. The Staging Bandwidth provides the required bandwidth for operation. When a large and quick change in system load occurs, the Override Bandwidth overrides the Staging Bandwidth to prevent immediate response to a short duration load change. An Override Bandwidth Timer can be programmed to prevent staging until the system load has stabilised and normal control established.

When the Pack Controller is enabled and running normally, and the frequency converter issues a trip alarm, staging and destaging xed speed compressors maintain the system head pressure. To prevent frequent staging and destaging and minimise load uctuations, a wider Fixed Speed Bandwidth is used instead of the Staging bandwidth.

0-12 This Set-up Linked to

Option: Function:

To enable conict-free changes from one set-up to another during operation, link set-ups containing parameters which are not changeable during operation. The link will ensure synchronizing of the ‘not changeable during operation’ parameter values when moving from one set-up to another during operation. ‘Not changeable during operation’ parameters can be identied by the label FALSE in the parameter lists in

chapter 6.16 Parameter Lists.

Parameter 0-12 This Set-up Linked to is used by

Multi set-up in parameter 0-10 Active Set-up. Multi set-up is used to move from one set-up to another during operation (i.e. while the motor is running). Example: Use Multi set-up to shift from Set-up 1 to Set-up 2 whilst the motor is running. Program in Set-up 1 rst, then ensure that Set-up 1 and Set-up 2 are synchronized (or ‘linked’). synchronization can be performed in two ways:

After the link is complete, parameter 0-13 Readout: Linked Set-ups will read {1,2} to indicate that all ‘not changeable during operation’ parameters are now the same in Setup 1 and Set-up 2. If there are changes to a ‘not changeable during operation’ parameter, e.g. parameter 1-30 Stator Resistance (Rs), in Set-up 2, they will also be changed automatically in Set-up

Range: Function:

The default setting of most of the parameters in the frequency converter (e.g. motor data, limits, ramps etc.) depends upon the compressor and system refrigerant selected for the frequency converter. The frequency converter selects the default compressor based upon the power size and voltage range for the frequency converter. Under normal circumstances this should not be changed. During test/repair situations a dierent compressor can be selected – or if the system is not using the default refrigerant.

Enter the motor speed to be attained as a start signal for commencement of PID control. When the power is switched on, the frequency converter will commence ramping and then operate under speed open loop control. Thereafter, when the Process PID start speed is reached, the frequency converter will change over to Process PID control.

7-33 Process PID Proportional Gain

Range: Function:

The FF factor sends a constant fraction of the reference signal to bypass the PID control, so the PID control only aects the remaining fraction of the control signal. Any change to this parameter will thus aect the motor speed. When the FF factor is activated it provides less overshoot, and high dynamics when changing the set point. parameter 7-38 Process PID Feed Forward Factor is active when parameter 1-00 Conguration Mode is set to [3] Process.

6.8.4 7-8* Thermostat/Pressostat Function

The Thermostat-Pressostat Function (TPF) can be used to stop and start the compressor when running in closed loop. The TPF monitors and compares the resulting feedback with the Cut-out value in parameter 7-81 Cut-out

Value. When the resulting feedback gets below parameter 7-81 Cut-out Value a stop signal is generated and

the compressor stops. When the resulting feedback gets above the Cut-in value in parameter 7-82 Cut-in Value the stop signal is removed and the compressor starts again.

The Set-point should be set to a value in between Cut-in and Cut-out.

Parameter Descriptions

Figure 6.12 Thermostat/Pressostat Function

Point A: At start-up the temperature will be higher than wanted in the evaporator and therefore a higher pressure than the Cut-in level and the compressor must run. Another situation could be that the start situation is where the feedback is between Cut-out and Cut-in. In that case, no STOP is initiated.

6.10 Par. Group 13 - Smart Logic Control

6.10.1 Prog. Features

Smart Logic Control (SLC) is essentially a sequence of user dened actions (see parameter 13-52 SL Controller Action [x]) executed by the SLC when the associated user dened event (see parameter 13-51 SL Controller Event [x]) is evaluated as TRUE by the SLC. The condition for an event can be a particular status or that the output from a Logic Rule or a Comparator Operand becomes TRUE. That will lead to an associated Action as illustrated:

When the last event/action has been executed, the sequence starts over again from event [0]/action [0]. The illustration shows an example with three event/actions:

Figure 6.14 Events and Actions

Starting and stopping the SLC:

Starting and stopping the SLC can be done by selecting .On [1]. or .O [0]. in parameter 13-00 SL Controller

Mode. The SLC always starts in state 0 (where it evaluates event [0]). The SLC starts when the Start Event (dened in parameter 13-01 Start Event) is evaluated as TRUE (provided that On [1] is selected in parameter 13-00 SL Controller Mode). The SLC stops when the Stop Event (parameter 13-02 Stop Event) is TRUE. parameter 13-03 Reset SLC resets all SLC parameters and start programming from

scratch.

NOTICE!

SLC is only active in AUTO mode, not Hand On mode

Figure 6.13 Smart Logic Control (SLC)

6.10.2 13-0* SLC Settings

Events and actions are each numbered and linked together in pairs (states). This means that when event [0] is fullled (attains the value TRUE), action [0] is executed. After this, the conditions of event [1] will be evaluated and if evaluated TRUE, action [1] will be executed and so on. Only one event will be evaluated at any time. If an event is evaluated as FALSE, nothing happens (in the SLC) during the current scan interval and no other events will be evaluated. This means that when the SLC starts, it evaluates event [0] (and only event [0]) each scan interval. Only when event [0] is evaluated TRUE, will the SLC execute action [0] and start evaluating event [1]. It is possible to programme from 1 to 20 events and actions.

Use the SLC settings to activate, deactivate and reset the Smart Logic Control sequence. The logic functions and comparators are always running in the background, which opens for separate control of digital inputs and outputs.

6.10.3 13-1* Comparators

Comparators are used for comparing continuous variables (i.e. output frequency, output current, analog input etc.) to xed preset values.

Figure 6.15 Comparators

In addition, there are digital values that will be compared to xed time values. See explanation in parameter 13-10 Comparator Operand. Comparators are evaluated once in each scan interval. Use the result (TRUE or FALSE) directly. All parameters in this parameter group are array parameters with index 0 to 5. Select index 0 to programme Comparator 0, select index 1 to programme Comparator 1, and so on.

The results of parameter 13-40 Logic Rule Boolean 1,

parameter 13-41 Logic Rule Operator 1 and parameter 13-42 Logic Rule Boolean 2 are calculated rst.

The outcome (TRUE/FALSE) of this calculation is combined with the settings of parameter 13-43 Logic Rule Operator 2 and parameter 13-44 Logic Rule Boolean 3, yielding the nal

6.10.5 13-2* Timers

Use the result (TRUE or FALSE) from timers directly to dene an event (see parameter 13-51 SL Controller Event), or as boolean input in a logic rule (see parameter 13-40 Logic

Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2 or parameter 13-44 Logic Rule Boolean 3). A timer is only FALSE

when started by an action (i.e. [29] Start timer 1) until the timer value entered in this parameter is elapsed. Then it becomes TRUE again. All parameters in this parameter group are array parameters with index 0 to 2. Select index 0 to program Timer 0, select index 1 to program Timer 1, and so on.

13-20 SL Controller Timer

Range: Function:

Enter the value to dene the duration of the FALSE output from the programmed timer. A timer is only FALSE if it is started by an action (i.e. [29] Start timer

1) and until the given timer value has elapsed.

6.10.6 13-4* Logic Rules

Combine up to 3 boolean inputs (TRUE/FALSE inputs) from timers, comtors, digital inputs, status bits and events using the logical operators AND, OR, and NOT. Select boolean inputs for the calculation in parameter 13-40 Logic Rule

Boolean 1, parameter 13-42 Logic Rule Boolean 2 and parameter 13-44 Logic Rule Boolean 3. Dene the operators

used to logically combine the selected inputs in

parameter 13-41 Logic Rule Operator 1 and parameter 13-43 Logic Rule Operator 2.
