Commissioning:
1. Check all electrical connections (Figs. 2
and 3).
2. Make sure that the controller software is
EET.
3. Check / Set Bit Switches (Fig. 1).
4. Switch the controller ON.
5. Connect Set-up Unit to DIN Box Display
or controller (Fig. 2).
6. Check / Set operating parameters - see
list
7. Save values - if changed
8. Log the controller on to the network then
verify settings on Genus InTouch panel,
Set-up Unit or DIN Box Display.
9. Faults ?..........See ‘Fault Finding’.
Fault Finding:
Set-up Unit does not reach the first
screen.
•
If the red LED beside the display
connector is ON, then the controller is
faulty.
You cannot log the controller on to
the network.
•
There may be a controller with the same
name, already logged on the network.
•
There may be a maximum 32 controllers
already on the network segment.
•
Check on the InTouch panel, P.C. or
Supervisor.

Output Connections (Fig. 3):
The diagram on the left shows the output
connections to the EEV and suction line valves,
SGV, defrost heater, drip pan heater, remote,
and alarm. The connection to the EPR valve is
made from the front panel, at the two-pin
connector labelled ‘EPR valve’.
A special cable is provided for the network
connection. Neighbouring controllers can be
linked together to form a network by connecting
these cables in series.
