    The use of shielded wires is recommended. For Pt100 (resistance temperature detector), use identical wires of low lead resistance and no resistance difference among 3 wires. 4. Terms and Various Functions Program run * The following number of steps is fixedly set, depending on the number of patterns. Pattern No.

  • Page 9: Wait Function

    Wait function For the current step transferring to the next step, the next step does not begin if PV has not reached the wait zone (similarly, if PV has overreached) after the step time elapsed. However, if the wait time elapses, the next step begins at that point. The above operation is executed by selecting 0 to 4 for each step, or by setting value for 1 to 4.
  • Page 10 Time signal output At starting each step, the time signals 1 to 4 are turned on upon elapse of the time set on the ON delay timer. Then, the output is turned off upon elapse of the time set on the OFF delay timer. During the time signal output ON, corresponding lamps of TS1 to TS4 light up.
  • Page 11 The step changes when the external contact open (OFF) changes to the external contact closed (ON) during a program run. 4.11.4 Patterns 1 to 4 DI A pattern is selected from 1 to 15, which are configured by combination of the external contacts 1 to 4 closed (ON) and open (OFF).
  • Page 12 4.13.2 Operation amount current limiter The operation amount and current value are limited at each point obtained by dividing SLL to SLH into 10. At the operation amount limiter points 1 to 11, the operation amount resulted from calculation is limited. At the current value limiter points 1 to 11, the operation amount is limited by the operation amount at the current value limiter point determined from a measured current value and present operation amount if the measured current value at each point exceeds the value [setting value - current limiter sensitivity].
  • Page 13 Example: Assume the following for various settings and PV: PV = 120 ° C, operation amount limiter point 2 = 75.0%, current value limiter point 2 = 10.0 A, present operation amount = 60.0% and AHC = 1.0 A. − If measured current valued = 15 A: Based on the relation [0 to present operation amount (60.0%) = 0.0 to measured current value (15.0 A)], the operation amount [current value limiter point 2 (10.0 A) - current limiter sensitivity (1.0 A)] is to be determined.

    4.14.3-2 Primary/secondary control operation amount increase time Setting items: Primary/secondary control operation amount increase time: 0 to 3600 [second] (no function by setting at 0 [second]) Operation description: For a remote run, apply a limit on the operation amount such that the ratio of the operation amount to the calculated operation amount is from 0% at the start to 100% at the setting time.
  • Page 15 4.16 PV filter setting 4.16.1 PV filter setting This setting is a function to achieve the CR filter effect on the software by performing a primary delay calculation on the PV of the input 1. The filter effect is set with the damping time constant [t]. (Damping time constant is defined as time when PV reaches about 63% in a stepwise change of input.) * CR filter: Filter of first order lag Application of a PV filter:...
  • Page 16 4.17 Event alarm By setting the events 1 to 4 function setting, outputs of EV 1 to 4 are turned on if PV is located within the alarm range. Corresponding EV1 to EV4 lamps light up. By switching over the events 1 to 4 polarities, selection of open/closed is possible at the turn-on. Output is also turned on at occurrence of a loop abnormality when the events 1 to 4 function 2 setting is effective.
  • Page 17 4.20 Electric Power Outage Function − Upon recovery of the electric power after its outage during a run, the status at the time of the outage is restored under the following conditions. Note that, if the PV at restoration is out of the range of [PV ± electric power outage restoration temperature width], the restoration is made as a stop.
