BATTERY
The printed circuit board monitors the status of the back-up batteries.
If the control unit is supplied with power from the back-up batteries, the
yellow light-emitting diode flashes on and off showing that the 230 V
mains supply is interrupted.
If the batteries are not connected or defective, the yellow light-emitting
diode is on permanently showing that the batteries should be connected
or replaced. This is also the case if the 25 A fuse is defective. In all three
cases, an acoustic alarm sounds.
Note:
If the back-up batteries are heavily discharged, the yellow light-
emitting diode flashes on and off and the green OPERATION diode on
the circuit board is on until the batteries are fully charged.
ERROR - MOTOR 1
The printed circuit board monitors for defects in the cable from motor
terminal 1 (used in control units KFC 210 and KFC 220).
If the cable is interrupted, the yellow light-emitting diode flashes on and
off. If the cable is short-circuited, the yellow light-emitting diode is on
permanently.
The error is also indicated in the integrated break-glass point and pos-
sible additional break-glass points.
ERROR - MOTOR 2
The printed circuit board monitors for defects in the cable from motor
terminal 2 (used in control unit KFC 220 only).
If the cable is interrupted, the yellow light-emitting diode flashes on and
off. If the cable is short-circuited, the yellow light-emitting diode is on
permanently.
The error is also indicated in the integrated break-glass point and pos-
sible additional break-glass points.
ERROR - SMOKE DETECTOR
The printed circuit board monitors for defects in the cable to any smoke
detectors that are connected.
If the cable to the connected smoke detector(s) is interrupted, the yellow
light-emitting diode flashes on and off. If the cable is short-circuited, the
yellow light-emitting diode is on permanently.
The error is also indicated in the integrated break-glass point and pos-
sible additional break-glass points.
