CONTROL CENTER ST-1440
1 GENERAL DESCRIPTION
ST-1440 is a microprocessor-based control center for SAFEGREASE, SAFEOIL and
MULTILUBE lubrication systems. The control center can be used for controlling 1 to 14
separate lubrication channels or systems. ST-1440 controls lubrication according to its settings
and it also saves the lubrication event history onto a CPU-card. It will send an alarm to the
system for possible malfunction immediately.

2.2 Channel module CM1440
2.2.1 General
Channel module contains the control connections for one lubrication channel. Module is
connected to the CPU-unit, which controls the channel outputs and saves the channel input, via
a serial bus interface. A designated channel number has been preprogrammed for each
module, and the number is also printed on the module cover.
The programming switch PR/RN for a channel module is in normal operation at position RN.
