Description

For control of intermittently operated single-line centralized lubrica-

tion systems, the compact pump units with 3 or 6 liter reservoirs

can be fitted with an electronic control unit.

Either:

• IG38-30-I, timer operation for

time-dependent control

• IZ38-30-I, counter operation for

load-dependent control

Functions

• Adjustable interval duration

• Non-adjustable pump dwell time

• Non-adjustable pressure build-up monitoring time

• Pump run time limitation

• Prelubrication (lubrication when the supply voltage is switched on)

• Fill level monitoring with detection of wire

breakage (WS switch contact opens when level is too low)

• Operation with 3-wire proximity switch possible

Preset parameters

IG38-30-I

• Interval time 1 minute (for time-dependent control)

• Monitoring time 60 seconds

• Pump dwell time 15 seconds

IZ38-30-I

• Interval time 1 pulse (for load-dependent control)

• Monitoring time 60 seconds

• Pump dwell time 15 seconds

Lubrication interval duration

In number of pulses of the external machine contact MK

Machine contact MK only required with counter

operation

(IZ38-30-I).

Control unit can be set to either 230 V AC or 115 V AC.

The pump motor's voltage setting cannot be changed.
