On-off 1-wire-spring Ex-i circuit
Integrated aux. switches max. 24 V/3A, 240 V/0,
25 A, min. 5V/10 mA, switching at 5° and 85°.
Supply at aux. switches must be the same like
supply of the actuator.
Ex-i circuit for passive
+ potential free push button
on site and safety temperatu-
re sensor (Type
FireSafe
...accessories)
! Attention !
If you use this type
of wiring the heater
does not work in
case of open contact.

Standard wiring = spring return in ~ 10 sec.
Additional wiring terminal 5 = spring return in ~ 3 sec.
