Mode of Operation
The time period for relay 1
starts when power supply is
applied.
At the end of the set time pe-
riod, relay 1 operates and the
time period for relay 2 starts.
At the end of the second set
time period, relay 2 operates
and both relays will not re-
lease until power supply is
interrupted.

Selection of function
DIP-switch selector 1
Relay 1 operates
first (pins 1,3 and 4), when the
DIP-switch at the front of the
housing is in OFF-position
Relay 2 operates
first (pins 8,9 and 10) when the
DIP-switch at the front of the
housing is in ON-position
Reverse function (pins 5 and 7)
Selection of time-range
T1: DIP-switch selector (2&3)
T2: DIP-switch selector (4&5)
0.15 - 3 s
0.6 - 12 s
5 - 100 s
40 - 800 s
Time setting
Knob-adjustable on scale in
per cent of max. time. DIP-
switch for selecting function
and time are placed behind a
small removable front on the
front of the time relay.

The order of the relays can be
inverted by means of a DIP-
switch at the front of the hous-
ing or by interconnecting pins
5 and 7 on the socket.
If power supply is interrupted
for at least 200 ms, the time
relay and time circuit are re-
set and the relay is ready for a
new time period.
