** Cautions for input selection

1) When you select input mode, you must shift jump switch inside of PCB to CORRECT position first.

2) Afterwards select each input mode by key operation.

PID Auto-Tuning (Valid in Relay and SSR output only)

• Press the key and key at the same time. Then,

AT indication lamp flashes to start the Auto-tuning

function.

• If Auto-tuning function ends, the AT indication lamp

stops flashing automatically.

When checking the auto-tuned value, press the key

and conform in turn.

• When you want Auto-tuning function to be suspended,

press the key and key simultaneously, then the

AT indication lamp stops flashing to release Auto-tuning

function. In this case P.I.D and ARW values are not

changed (Maintain the value before the Auto-tuning

starts).

• When you want to change the SV(set-value) during Auto-

tuning, suspend it and perform PID control using the

values before Auto-tuning starts.

Control loop break alarm(LBA)

LBA function starts to measure time from the moment

that the PID Computed Value (Output ON time/cycle)

become 0% or 100%, and detects the amount of Process

Value change at each LBA setting time, and determines by

the amount of change whether LBA is to be ON or OFF.

• When the status at a 100% PID computed value

continues beyond the LBA setting time, the LBA turns

ON if the measured-value(PV) does not rise by 2()

or more.

(In direct action, the above alarm turns ON if the

measured-value does not fall by 2() or more.

• When the status at 0% PID computed value continues

beyond the LBA setting time, the LBA turns ON if the

measured-value(PV) does not fall by 2() or more.

Remote input

Set-value of controller can be set or changed from outside

of the controller by direct voltage/current signal.

But the external signal should be input continuously.

(Auto-tuning function is not operated while the external

signal is set)

Heater break alarm(HBA)

Set-value of HBA to be set about 85% to input of CT but

the set-value should be less in case that the ratio of

voltage variation is high.

If several heaters are connected in parallel, the alarm may

be turned ON even though one circuit is broken.

In such a case, set the value of HBA to be slightly high.

No HBA operates at “O” setting, but HBA operates at

“25.0”or“50.0”setting.
