FUNCTION
With supply voltage applied to terminals A1/A2, relays K3 and K4
(terminals 37/38) start with the pre-selected ON-delay time. The
ON-delay time t
or 1.5 to 30 s according to the device type. The device is enabled by
pressing the reset button. The following operating modes can be
selected:
can be adjusted infinitely in the range 0.15 to 3 s

• Manual start – The reset button must be connected to S34
through terminal S33. For starting the relay, the reset button must
be pressed. Relays K3 and K4 (terminals 37/38) will switch into the
OFF position. With the falling edge of the reset signal, the reset is
completed and activates relays K1 and K2, which become
self-locking after the response time tA3. After this switch-on
phase, the 2 enabling current paths defined for the output are
closed (terminals 13/14, 23/24). With the emergency stop command, the power supply to relays K1 and K2 is interrupted. The
enabling current paths (terminals 13/14, 23/24) are immediately
opened with release time tR, and relays K3 and K4 will start after
the pre-set ON-delay time tA1, terminals 37/38. Three LEDs
display the state of relays K1/K2, K3/K4 and the supply voltage.
• Automatic start – For monitoring of interlocking installations
with locking mechanism or safety gate applications in which on
automatic start shall be performed it is necessar y to jumper
terminals S33/S35. The device will react at the rising edge of input
S12 that is internally connected to S33. Relays K3 and K4 (terminals 37/38) will switch into the OFF position. With the rising edge
of input S12 the relay K1 is activated and response time tA2
started. When the time has elapsed, the 2 enabling current paths
are closed (terminals 13/14, 23/24). With a stop command the
power supply to relays K1 and K2 is interrupted. The enabling
current paths (terminals 13/14, 23/24) are immediately opened
with release time tR, and relays K3 and K4 will start after the
pre-set ON-delay time tA1, terminals 37/38.
