Range
Working
Do all connection according to circuit diagram.
-Relay will be working as per following modes.
1) Control Mode PID: Relay turning ON/OFF according to heat requirement of the
machine.
2) Control Mode ON/OFF: Relay turns ON (and remains ON) when PV < SV. Relay turns
OFF when PV > SV. After this there may be overshoot depending on the thermal
inertia of the machine. When the PV < SV Minus HYS, Relay turns ON and heating
is resumed.
1) Cooling Time proportional Control action: Relay turns ON/OFF as per set Cycle time
and difference between PV and cooling SV.
2) Cooling ON/OFF control action: Relay is initially OFF. When PV > SV, Relay turns ON
and when PV < SV Minus HYS relay turns OFF.
1) Heater Break alarm: - If the current of the Heater < AMP SV (unhealthy condition)
then Relay turns ON and Upper Display will show
,
middle display will blink

till the fault is rectified.

2) Cold start (CS) alarm: Relay is initially OFF. When PV > Alarm SV, Relay turns ON.
When PV < Alarm SV MINUS HYS, Relay turns OFF.
3) High Alarm: Relay is initially OFF. When PV > Alarm SV, Relay turns ON , And remains
ON up to set Alarm time. Alarm is reset when temp. of PV < Alarm SV MINUS HYS.
This action will repeat whenever temp goes beyond Alarm SV.
4) Absolute -Low alarm: Relay is initially OFF. Now for once PV will go above SV, then
when PV < alarm SV, then alarm relay turns ON and remains ON up to alarm time.
Alarm is reset when temp. of PV > Alarm SV+HYS. This action will repeat
whenever temp. goes beyond Alarm SV.
5) In band alarm:- Two Alarm SV has to be defined . Between these two values, Relay
turns ON up to set Alarm time. Below the band & above the band relay turns OFF.
6) Absolute outband alarm:- Two Alarm SV has to be defined. Relay is initially OFF.
Once PV goes in between band value, after this if it goes below the band or above
the band, relay remains ON until alarm time.

3) Set 2 is relative to Set 1. (e.g. Set1=100°C and Set 2 = 15°C then Set 2 is
becomes “115”)
4) For Heater Break Indication, if any phase Heater breaks down than upper display will
indicate
and middle display will show blinking
