WORKING PRINCIPLES

When parameter is equal to “1”, Starting of scanning  selonoids, device waits for break time, after that O1 output is activated. This output is active for pulse time, after that O1 output is deactivated. Device waits break time and same process repeats with the next selonoid. This process continues until number of outputs reach to parameter. When last output is deactivated at the end of pulse time, device starts to waiting time. After waiting that time, break time is started and O1 output is activated at the end of break time and repeats same process.
If start input of device is active, this process continues. After deactivation of start input, the device repeats this process for times and stop the process.
First of 8 outputs is used on the control unit. Output units must be used for more than 8 outputs.

In case the device parameter is greater than 1, 2 different operating type is available. This operating type is determined by the parameter. In applications where the number of groups is greater than 1, the group 1 output card is used as the selection card.
When the parameter is set to , the device works as shown in .
Figure 4.2 When scanning starts, O1 output of group card is energized and 1st Group is selected. break time is started. O1 output of the device is energized at the end of the break time period and the pulse time is started. At the end of the pulse time period, O1 is de-energized and break time is started again and the same operation is repeated until the number of output reaches the value of  parameter. When the last output is de-energized, O1 output of the group card is de-energized togetherly. group waiting time is started. At the end of the group waiting time period, the O2 output of the group card is energized and the 2nd Group is selected. The operations in the 1st group are repeated exactly. this group operations is repeated until the number of group reaches the value of parameter. At the end of the last group operation, waiting time period starts. After the waiting time period, 1st group is selected again and same operations are repeated.

When the parameter is set to , the device works as shown in
Figure 4.3 . When scanning starts, O1 output of group card is energized and 1st group is selected. break time is started. O1 output of the device is energized at the end of the break time period and the pulse time is started. At the end of the pulse time period, O1 is de-energized and break time is started again and the same operation is repeated until the number of output reaches the value of parameter. When the last output is de-energized, O1 output of the group card is de-energized togetherly. group waiting time is started. At the end of the group waiting time period, the O2 output of the group card is energized and the 2nd group is selected. The outputs of 2nd group starts from where the last output of 1st group, and scanning operation is repeated until the number of output reaches the value of parameter. As seen in the example, the last output of 1st group is energized O3 output, and the first output of 2nd group is energized O4 output. This group operations is repeated until the number of group reaches the value of parameter. At the end of the last group operation, waiting time period starts. After the waiting time period, 1st group is selected again and same operations are repeated.

If start input of device is active, this process continues. After deactivation of start input, device repeats this process for times and stop the process.
First of 8 outputs is used on control unit. Output units must be used for more than 8 outputs. One output unit is used to group selection unit. Selonoid supply of group selection unit (+VIN-) is connected to control unit (+VSIN-) terminal.
4.1. CONTROL TYPES
  parameter determines control type of the device, is selected as
If parameter is selected as , device doesn’t do any control during waiting times. Entire of waiting time is waited.
If parameter is selected as , if differential pressure value is higher than parameter, waiting time is skipped during   the process. If differential pressure value is lower than parameter, Entire of waiting time is waited during the process. If differential pressure value is between and parameters, device does the same as previous scanning.

If parameter is selected as , if differential pressure value is higher than parameter, waiting time is skipped   during the process. If differential pressure value is lower than parameter, Entire of waiting time is waited during the  rocess. If differential pressure value is between and parameters, waiting time is set between 0 and proportionally.

4.2. ALARM RELAYS

Rl1 and RL2 are alarm relays, that give alarm according to one or more than one alarm source. Alarm type of these relays are adjusted as normally open or normally closed.
Device gives alarm in case of break selonoid supply, open or short selonoids and high differential pressure value. These alarm sources are adjusted for both of the relays with and parameters, like as Table 4.2 . Alarm types of relays, that is normally open and normally closed are adjusted for both of the relays with  and  parameters, like as Table 4.1
When alarm relays are powered, user can acknowledge the alarm and deactivate the alarm relay according to and parameters. If these parameters are selected , user open error message page and deactivates relay, but led of relay continues to light. In this situation, error message of alarm is shown in error message page. Led of relay fades after alarm state. If these parameters are selected  , relay and led deactivates after the alarm state ends.

Table 4.2. Alarm Sources
4.2.1. OPEN / SHORT CIRCUIT ALARM

Device can give alarm, while short or open circuit happen on selonids. Device measures the selonoid line and controls any error on the selonoid line, before device powers the selonoids. If any error is occured on selonoid, device doesn’t power the selonoid and gives alarm, so that outputs of device don’t need any fuses. In the selonoids scanning, while the selonoid has any problem, device works differently according to parameter.
If parameter is selected , device waits and timing for that selonoid, but output doesn’t powered. If the parameter is selected , device doesn’t wait and timing, and continues next output. parameter determines open circuit state, parameter determines short circuit state. parameter should be set to half of the nominal resistance of the selonoids,   parameter should be set to two times of the nominal resistance of the selonoids.
4.2.2. HIGH PRESSURE ALARM
Device, that has pressure control gives high pressure alarm according to and parameters. If differential pressure is higher than parameter, device gives high pressure alarm. The alarm condition ends when the differential pressure reading decrease to  – .
4.2.3. NO SELONOID SUPPLY ALARM
If Selonoid supply of device, that is connected (+VSIN-) terminals is broken, device gives no selonoid supply alarm.
4.2.4. SCAN ACTIVE ALARM
When Start input of device that is in A24 (IN1) terminal is active, the device gives scan active alarm.
All of these alarms is shown on display to user. In addition, if device has RS-485 communication, the alarms can be read from Modbus protocol.
4.3. SCANNING ORDER OF OUTPUTS
Scanning order of the device starts with 1, and ends with 128 in factory settings. The scanning order can be configured using Modbus protocol. Register addresses of these order parameters are shown in Table 4.3

Tablo 4.3. Output Configuration Parameters Modbus Address Table
NOTE1 : Parameters, that shown in Table 4.3 are 16-bits. For example low 8-bits of OUT1-2 parameter shows first output, high 8-bit of OUT1-2 parameter shows second output. In below example, output 5 is powered firstly, output3 is powered secondly according to OUT1-2 parameter. Other parameters are configured the same method.

OUTPUT UNITS

Each output unit has 16 outputs. Output units communicate with control unit over DATA terminal. If this connection breaks, output unit doesn’t work. Power supply of output units are supplied with (+VSUP-) terminals. Each output unit, that is connected to control unit has an address. These adresses are configured via jumpers on output unit cards. More than one unit mustn’t have same adresses. Jumper configuration of addresses are shown in . Table 5.1
(+VIN-) terminals of output units must be connected to (-VOUT+) terminals of control unit. If any problem on that connection occurs, all of the selonoids are measured open circuit and any output isn’t powered. If filtering system has more than one group, one output unit must be used for group selction unit. Selonoid supply of this unit must be connected (+VSIN-) terminals of control unit.
