Manual to Automatic transfer:
When transferring from manual control to Automatic control there are two methods:
Bumpless Mode (without modification of set point) and Set Point mode (when the
current Set Point is modified it will be set to the actual measured input value). If in
Manual mode runs as open loop i.e SP is really the percentage output power, hence
how the transfer can be bumpless or SP change.
Input n Calibration
Set the percentage of range the calibration shunt resistor needs to be set at between
40%and 100%. Default 80%
Start Input n Low Point Calibration Press +keys to begin calibration procedure
Start Input n HIgh Point Calibration Press +keys to begin calibration procedure (Can only be accessed once a
successful low calibration has been completed)
Error Messages
Count Fail
means the low calibration will fail if the offset is less than -10mV or
greater than +10mV. This signifies potential faulty sensors or the high
calibration will fail if the count value is less than +20mV or greater than +50mV. This
signifies potential faulty sensors RCal Fail means the high calibration will fail if the
mV value is within 10mV of the low calibration value. This is a potential RCAL failure.
