with UV sensor or ionization sensor.
For intermittent or continuous operation.
Flame signal current:
ionization control: 1 – 25 μA,
UV control: 1 – 35 μA.
Ionization cable, UV cable:
max. 100 m (164 ft).
Contact rating:
valve outputs V1, V2, V3 and V4 (terminals 13, 14,
15, 57) as well as actuator (terminals 53, 54
and 55):
max. 1 A each, cos φ ≥ 0.6,
total current for the simultaneous activation of the
valve outputs (terminals 13, 14, 15, 57) and of the
actuator (terminals 53, 54, 55):
max. 2.5 A,
fan (terminal 58):

Designed lifetime
This information on the designed lifetime is based on
using the product in accordance with these operating
instructions. Once the designed lifetime has been
reached, safety-relevant products must be replaced.
Designed lifetime (based on date of manufacture):
20 years.
You can find further explanations in the applicable
rules and regulations and on the afecor website
(www.afecor.org).
This procedure applies to heating systems. For
thermoprocessing equipment, observe local regu-
lations.
Logistics
Transport
Protect the unit from external forces (blows, shocks,
vibration). On receipt of the product, check that the
delivery is complete, see page 2 (Part designa-
tions). Report any transport damage immediately.
Storage
Store the product in a dry and clean place.
Storage temperature: see page 22 (Technical data).
Storage time: 6 months before using for the first
time. If stored for longer than this, the overall service
life will be reduced by the corresponding amount of
extra storage time.
Packaging
The packaging material is to be disposed of in ac-
cordance with local regulations.
Disposal
Components are to be disposed of separately in
accordance with local regulations.
