6.1.5 Connecting the signal tower
Purpose of a signal tower
A signal tower that is electronically connected to the combi oven indicates the current operating status
of your combi oven visually, using three indicator lamps (green, yellow, red), and acoustically. This in‐
dicating device provides a signal that can be seen and heard from far away.
Accessories required
The signal tower is supplied with the following original accessories, which you will need in order to
connect the signal tower to the combi oven:
■
Connecting cable (approx. length 10 m) with M12 female connector
■
DN 50 diaphragm grommet
In addition you will need the following equipment:
■
Cable ties
Connecting the signal tower
The figure below shows a size 12.20 combi oven as an example for all appliance sizes:
1.
Disconnect the combi oven from the power supply.
2.
Remove the side panel from the combi oven in order to
access terminal block X32 (2) on the system interface
board (SIB) (1) in the area behind the operating panel.
3.
■
Tap out the larger, pre-perforated knock-out in the floor
panel of the combi oven, at the position indicated.
■
Insert the diaphragm grommet in the knock-out then
feed the signal-tower connecting cable through the
grommet into the wiring compartment of the combi
oven.
■
Take the connecting cable to the SIB and fix it in the
wiring compartment, for instance using cable ties to at‐
tach it to an existing wiring harness.
