Pressurization extra delay time
Pressurization extra delay time is used, when grease lubrication systems (SG1, SG2 and
SG2E) are in pressure switch mode. Delay time is set maximum pressurization time multiplied
by delay multiplier. The delay multiplier can be set at configuration mode.
Pressurization extra delay time is the minimum time between two pressurization phases. When
the delay setting prevents pressurization, the phase code Delay is displayed along with the
delay time left.
Pressure discharge
In pressure transmitter operation, line pressure discharge is waited. New pressurization phase
can be started only after pressure in both lines is below the set low limit value.
When center is waiting for pressure discharge, the phase Discharge and the elapsed
discharge time are displayed. Center goes into alarm mode, if the discharge time is longer than
interval time (= lubrication cycle/2).

Phase description
Channel is at interval counting mode
The channel is in pressurization phase
Interlocking switch is closed
(The switch is monitored only during
intervals)
The channel is waiting for pressurization
because of another channel being
pressurized or if the pressurization phase
for another channel has stopped less than
30 seconds ago.
