11. Various type of option
As for this instrument, various options are prepared.
Name of option Function
PID current output type 1 to 5mA Output signal of current output type PID is outputted by 1 to 5mA.
PID voltage output type ±10V Output signal of voltage output type PID is outputted by ±10V.
1 to 5V Output the signal which is proportional to setting value,
measurement value, output value, and etc.
Output signal: 1 to 5V
Transmission
output
(High accuracy
type)
1 to 5mA Output the signal which is proportional to setting value,
measurement value, output value, and etc.
Output signal: 1 to 5mA
Output scaling This is the function which is scaled control output signal, and also
can be used gain adjustment of firing unit of thyristor.
Scaling range: -5% to 105%
* Scaling calculation is not performed during manual operation.
Alarm output phase Output phase of 4 points alarm output (AL1 to Al4) reflex only
during power distribution.
Damp proofing Damp proof inside printed board.
Output limiter OFF Output value is not limited by output limiter during manual
operation.
Manual output range: -5% to 105%
Communication 1 port
Select zone 1 Communication 1 port can be selected in zone 1.
Communication type: select one of RS-232C, RS-422A, and
RS-485
Screen return OFF When key is not operated for 3 minute on the setting screen, not
return to the operation screen.
Output 2 of judgment for heater
snapping wire (short-circuit) alarm When both output 1 and output 2 are ON-OFF pulse type or SSR
drive pulse type, heater snapping wire alarm is judged in output 2.
Heater short-circuit alarm
Heater current value is measured when control is OFF for judging
abnormal short-circuit status of heater and alarm judgment is
performed
Square roots calculation Direct voltage or direct current input is performed square roots
calculation, and then measurement value (PV) is displayed and
control calculation is performed.
Time signal output OFF during
FAST Time signal output is OFF during operating FAST.
Lower limit burn out Display of PV is followed through to lower limit, and lower limit
alarm is outputted at burn out.
Gradient setting Setting method of program pattern can be set by gradient value and
duration time from target value and time required.
Open loop method of ON-OFF
servo Time control is performed not using feedback resistance of control
motor at ON-OFF servo type PID.
