6.5 Electrical connections
The user should carry out three electrical connections to the central
unit, namely:
• the power supply connector
(† pos. 4 fig. 15)
• the connector for the proximity sensor
(† pos. 3 fig. 15)
• the connector for the default output
(† pos. 1 fig. 15)
• the fourth connector
(† pos. 2 fig. 15)
is optional for external
connection of the level-contact
6.5.1 Power supply
The power supply of the CLK central unit is 230 V~, 50/60 Hz (vol-
tage key + 428) or 115 V~, 50/60 Hz (voltage key + 429).
For the pin assignment on the power supply connector, see Table
2.

6.5.2 Fault output
The user can connect the fault output to an external light signal or to
its control panel. The user can therefore get more easily the fault
information.
For the pin assignment on the fault output connector, see Table 3.
6.5.3 Proximity sensor
An inductive proximity sensor is placed at the chain. It detects the
passage of the lubrication points. When the system is in lubrication
phase, the sensor sends a signal to the control unit each time it
detects a lubrication point. The control unit triggers an lubrication
pulse.
For the pin assignment on the proximity sensor connector, see
Table 4.
WARNING
Only qualified, instructed specialists who are authorized by
the operator may install the electrical connections for the
lubrication unit. The connection conditions and the local
regulations (e.g. DIN, VDE, NF) must be scrupulously res-
pected. If systems are improperly connected, substantial
material or personal damage my be the consequence.
WARNING
The supply voltage on site must agree with the information
on the codification of the lubrication system. Check the
fusing of the circuit. Use only the original fuse with the
required ampere value. If other fuses are used, damage to
property of personal injury may be the consequence.
