16 .1 Electrical data

Mains voltage
BCU..Q: 120 V AC, -15/+10%, 50/60 Hz, ±5%,
BCU..W: 230 V AC, -15/+10%, 50/60 Hz, ±5%,
for grounded or ungrounded mains.
Power consumption
At 230 V AC approx. 6 W/11 VA plus power consump-
tion per AC input of approx. 0.15 W/0.4 VA,
at 120 V AC approx. 3 W/5.5 VA plus power consump-
tion per AC input of approx. 0.08 W/0.2 VA.
Flame control
With UV sensor or ionization sensor,
for continuous operation (intermittent operation with
UVS).
Flame signal current: ionization control: 2 – 25 μA,
UV control: 5 – 25 μA.
Signal cable for flame signal current: max. 100 m
(164 ft).
Contact rating
– Valve outputs V1, V2, V3 and V4 (terminals 13, 14, 15
and 57):
max. 1 A each, cos ϕ ≥ 0.6.
– Actuator outputs (terminals 53, 54 and 55):
max. 1 A each, cos ϕ = 1.
BCU 580 · Edition 11.15l
– Ignition transformer (terminal 9):
max. 2 A.
– Total current for the simultaneous activation of the
valve outputs (terminals 13, 14, 15 and 57), the actu-
ator (terminals 53 – 56) and the ignition transformer:
max. 2.5 A.
– Signalling contact for operating and fault signals:
max. 1 A (external fuse required).
Number of operating cycles
The fail-safe valve outputs V1, V2, V3 and V4 are moni-
tored for correct functioning and are thus not subject to
a max. number of operating cycles.
Actuator (terminals 53, 54 and 55): max. 1,000,000,
signalling contact for operating signals: max.
1,000,000,
signalling contact for fault signals: max. 10,000,
On/Off button: max. 10,000,
Reset/Information button: max. 10,000.
