[Resetting a fault]
(a) Resetting all the circuits of a module using a unit controller
To reset a fault, touch STOP on the operation panel located inside the power box of a module. Upon fault
reset, the Remote/Unit switch is automatically set to Unit module. After you fix the cause of the fault, set it
back to Remote Group.
(b) Resetting a fault using the module controller
If the operating mode is External or Remote, a stop signal from an external device (e.g., a central supervisory
board) or a remote device (i.e., optional group controller) cannot be used to reset a fault. Use the LCD screen
of the module controller to turn off the associated modules, which resets the faults. In this case, a fault reset is
performed for all modules connected to the module controller. Upon fault reset, the operating mode is
automatically set to Unit. After you fix the cause of the fault, set it back to External or Remote.
* A custom option is available for supporting a fault reset using an external or remote stop signal.
For details, contact Toshiba Carrier.
(c) Resetting a fault using the optional group controller
If the current operating mode is External or Remote, a stop signal from an external device (e.g., a central
supervisory board) or a remote device (i.e., custom Web monitor) cannot be used to reset a fault. Use the
LCD screen of the group controller to turn off the associated modules, which causes the faults of all the
connected module controllers and unit controllers to be reset. Upon fault reset, the operating mode is
automatically set to Unit. After you fix the cause the fault, set it back to External.
* A custom option is available for supporting a fault reset using an external or remote stop signal.
