BCU..W: 230VAC, -15/+10%, 50/60Hz, ± 5%.
Power consumption: 10VA,
for grounded and ungrounded mains.
Flame control:
with UV sensor or flame rod.
For intermittent or continuous operation.
Flame signal current:
Ionization control: 1 – 25 �A,
UV control: 1 – 35 �A.
Ionization cable, UV cable:
max. 50 m (164ft).
Contact rating:
Valve outputs V1, V2, V3 andV4 (terminals60, 61, 62,
63 and64): max.1A each, cosφ =1 .
Actuator outputs (terminals 65, 66 and 67): max.1A
each, cosφ=1.
Air valve output (terminal 65): max.1A, cosφ=1.
Ignition transformer (terminal 51): max.2A.
Total current for the simultaneous activation of the
valve outputs (terminals 60, 61, 62, 63 and64) and of
the ignition transformer (terminal51), protected by F1/
F2: max.2.5A.
Total current for the simultaneous activation of the
outputs for air valve and actuator (terminals 65, 66
and67): max.2A.
Signalling contact for operating and fault signals:
max.1A, cosφ=1 (external fuse required).
Number of operating cycles:
The fail-safe outputs (valve outputs V1, V2, V3 andV4)
and the air valve output are monitored for correct func-
tioning and are thus not subject to a max. number of
operating cycles.
Control actuator (terminals60, 61, 62, 63 and64):
1,000,000,
signalling contact for operating signals (terminals 95,
96 and97):
1,000,000,
signalling contact for fault signals (terminals 80, 81
and82):
max. 25,000,
On/Off button:
max. 10,000,
Reset/Information button:
max. 10,000.
