Screw terminal 6:
Common GND connection for all inputs
Screw terminal 7:
(–) external power supply for the backlight option
Screw terminal 8:
(+) external power supply for the backlight option
(24 V DC ±20 %, 50 mA), Fuse T0.08 A, delayed action
All low voltages, SELV, reinforced/double
insulation.
Signal inputs must be protected with an exter-
nal delayed T0.01 A fuse when the source
does not provide protective impedance (fuse/
current limitation).

Electrical locking of the reset key
Contact input / Open Collector NPN
(switching at 0 V DC)
Low level: 0…0.7 V DC
High level: 3…5 V DC
Input resistance: approximately 2.2 MOhm
Input not active: Reset key locked
Input in contact with GND:
Reset key unlocked
Screw terminal 5:
Time range switching (Mode)
Contact input / Open Collector NPN
(switching at 0 V DC)
Low level: 0…0.7 V DC
High level: 3…5 V DC
Input resistance: approximately 2.2 MOhm
Function: see table 3
Note:
If the time range is changed during operati-
on, the device must be reset, otherwise the
counting value will not be reproducible.
