Operation
Operating modes
The device works with pulse control through the connection of
an external controller (PLC). A corresponding program must be
created in the PLC to operate the lubricator.
An input and an output must be provided on the control side to
integrate the lubricator into an external controller.
Input signals at PIN 2 are transmitted by the controller.
Output signals at PIN 4 can be picked up via HIGH/LOW level
for further processing (for example, indicator lights or external
controller).
NOTICE
Exceeding the output current will cause serious damage to the
device. The maximum permissible output current must not exceed
I
max
⬍
20 mA. Do not connect an inductive load (for example,
relay).
 
The lubricator can be switched off completely by shutting off
the supply voltage. Once the supply voltage has been reconnected,
the device carries out an automatic check and works after receiving
an input signal from the PLC.
4-pin plug,
connector assignment
Power is supplied via PIN 1 and PIN 3. The PLC must send a control
signal to PIN 2. The lubricator transmits signals to the PLC via PIN 4.
A signal has one of the following two states:
■
HIGH
■
LOW.
