Tornatech GPX User Manual

Most common timers for the transfer switch control can be configured here. Note that any timer set to 0 will remove
the delay in the decision process.
Access level 1:
- Cooling Time: Time delay after which a running generator can be shut down when all running causes have return
to normal.
- Retransfer time: Time delay used to re-qualify the normal power and retransfer. Typically five minutes.
Voltage Calibration
Config > Advanced > Voltage
To calibrate the voltage sensing element of a power source, enter the 3 phase voltages as read on a calibrated
meter then press compute. In the case of a transfer switch model, 3 additional voltages need to be calibrated the
same way.
Current Calibration
Config > Advanced > Current
To calibrate a particular current sensing element, enter the current value as read from a calibrated ammeter and
then press COMPUTE. For best results, press the ZERO button when no current is flowing through the sensing
element before calibrating.
