This parameter will be prompted only if selected control action is PID.
This parameter will decide the maximum output power in % applied to
the load.

100.0 Sec.
This parameter will be prompted only if selected control action is PID.
User can set this value based on process being controlled & type of
output being selected. For Relay O/P, cycle time should be more than
12sec & for SSR O/P, cycle time should be less than 10sec.

This parameter will be prompted only if selected control action is PID. It
defines how strongly the controller will react to rate of change of PV.
Value of this parameter is automatically set by auto tune function. If set
to ‘0’, this function will be disabled.
0
to
9999 Sec.
This parameter will be prompted only if selected control action is PID. It
sets the time taken by PID algorithm to remove steady state error. Value
of this parameter is automatically set by auto tune function. If set to ‘0’,
this function will be disabled.
0.5

This parameter will be prompted only if selected control action is PID. It
sets proportional band over which the output power is adjusted
depending upon the error (SV-PV). Value of this parameter is
automatically set by Auto tune function.
CONTROL LIST : To enter in this mode, press SET & DOWN key simultaneously for 3 sec. User can then set the
following control parameters.

This parameter will be prompted only if selected control action is PID.
With this parameter O/P will be Completely OFF after the Set Point +
Offset Value. If Disable, O/P will act Depending upon the PID Value
after Set Point achieved.
This parameter is prompted only if output 2 is configured as soak timer.
Controller starts the execution of soak time as per the mode selected.
Soak timer can be programmed using four different time base in Config.

(1)
Either absolute auxiliary control or as an alarm (High/Low) mode.
(2)
Either deviation auxiliary control or as a deviation alarm mode.
(3)

User can change SP1 value using UP/ DOWN keys. Holding the key,
will change the value at a faster rate. Press SET key to store the
desired value & move on to the next parameter.
User can set ramp rate/min for SP1 (Set Point) to minimize overshoot.
This parameter will be available only if Enabled in Configuration List.

Output 2 will be automatically activated /de-activated w.r.t SP1 & HYS.
This parameter is prompted only if Control Logic for Output1 is

Output 2 will be permanently Activated (ON).
Output 2 will be permanently De-Activated (OFF).
User has a choice to set different Lock Code via USER LOCK CODE in

This parameter will be prompted only if selected control action is PID.
This parameter allows the User to carry out Auto Tuning function below
the set point. (If tune offset is set to 50 %, tuning will be carried out at
50 % of the set point and if set to 100 %, tuning will be carried out at
100 % of the set point.)
