bS PV Bias - Expressed in degrees from –199 to 999. This parameter is used
to set the actual oven temperature to the controller display.
LoC Key Lock - This provides levels of access to the controller.
0 = No key lock, full access to controller.
1 = Prevents changing of all parameters except setpoint.
2 = Prevents all parameters from being changed including the setpoint.
-1 = Set to enter the Setup parameter setting display.
The controller is set to LoC=1 at the factory. This prevents inadvertent changing
of control parameters with the exception of setpoint.
If it becomes necessary to alter control parameters, change the LoC=1 to LoC=0.
Follow the parameter programming mode found earlier in this manual.
When LoC = -1, the parameters are displayed in the order shown in the Set-Up
Parameters section, below. Note: If you are unable to change the setup
parameters, go back out and change the LoC = 0. Press the
key until LoC
appears again, change LoC = -1 and press the key.
