b Combined with an impulse relay, b Combined with an impulse relay, b Allows the step by step sequence
b Used to control impulse relays
it operates on latched orders
it automatically disconnects the over circuits
by illuminated push-buttons,
circuit after a preset time
without operating risks
– b 5 time setting ranges:
v 1 to 10 s
v 6 to 60 s
v to 10 min
v 6 to 60 min
v to 10 h
iTL1 iTL2
The cycle is as follows:
1st impulse - iTL 1 closed, iTL open
nd impulse - iTL 1 open, iTL closed
3rd impulse - iTL 1 and closed
4th impulse - iTL 1 and open
5th b

b Provide an iATLz when the
current drawn up by the illuminated
push-buttons is higher than 3 mA
(this current is sufficient to keep
the coils energised). Above this
value, fit one extra iATLz per 3 mA.
b For example: for 7 mA,
fit 2 iATLz
