PERATION
-
After the self test sequence, if the device is ready for operation, states and operation of the module and
its units are shown as follows:
-
‘COM’ LED
– indicates the communication with the unit that belongs to it, (all LED-s flash in case of
communication with the module), it also indicates the operation state of the device.
-
‘STATUS’ LED
– indicates the state of the unit that belongs to it.

SETTING THE CURRENT GENERATOR AND RELAY OPERATION
Depending on the application, re-programming of the device may be needed. Programming can be done
with either a PC that controls the communication network via HART or MODBUS protocol, or a
MultiCONT

AND LOADING
FACTORY DEFAULTS
The mentioned operations can be done, without restarting the device, with the small recessed
‘RESET(TEST)’ button on the front panel:
RESET:
- Press
Entering TEST mode:
- Press and Hold
Loading factory default settings: - Hold pressed while power on, and release when all LEDs flash red.
Attention! The current generator units should be recalibrated!
The HART long addresses will change!
T
EST MODE
Once in test mode by consecutive pressing the
‘RESET(TEST)’
button you can cycle through the
following tests. Pressing this button until all Red LED-s are flashing will exit the test mode, without
pressing the button the device quits test mode after 30 seconds.
