Start Up Examples
MSR as Compressor Compound Controller
Requirement:
4 single compressors, stage 1 configured for
emergency operation, automatic base-load
change.
Control setpoint 2 bar, neutral zone 0,5 bar.
pressure transmitter 4-20 mA, range 0-10 bar.
Night operation (2nd setpoint) within 19:00 and
7:00, 0,5 bar higher. Forward/Backrun delay 10
sec. The user want to see the actual pressure
value on a remote display with 0-10V-input. While
a peak load limitation via OK 1, 2 stages remain
for control purposes.

Push and hold key 'P', switch ON power
•
Hold key 'P' until '_ _ _' appears
•
Let go key 'P'
•
Select '1 _ _' by key '

'
(compressor compound mode)
•
Push key 'P' once
•
'def' appears, default values are loaded
•
Actual values appear, ready for start up.
Basic Configuration
Enter Code Number '70' at P48

(analog output delivers 10VDC at 10bar)
•
P43=0
(analog output delivers 0V at 0 bar)

Display correction
The actual pressure display P01 can be calibrated
by using P29.
MSR as Condenser Fan Controller

each. Pressure transmitter 4-20 mA, range 0-25
bar. Night operation (2nd setpoint) within 20:00
and 6:30, 2 bar higher. Forward/Backrun delay 30
sec.
