8.2 Configuring CM-SW-01 with the BEST Software
In its state of delivery, the compressor control module
CM-SW-01 is completely configured for use with the
OS.A95. An adjustment of these data is not required;
date and time, however, should be checked and modi-
fied if necessary. Depending on the system design, it
may be useful to adjust some other parameters.
8.2.1 Setting the current time
Check the programmed date and time using the BEST
Software:
• Check the CONFIGURATION menu, the MAIN SETUP win-
dow and the DATE and Time lines.
• Correct the data if necessary.
8.2.2 Changing the limit values for high and low
pressure
In the state of delivery, the limit values for high pres-
sure and low pressure cut-out are set to 28bar and
-0.6bar in relative pressures, respectively. Depending
on the system design, these values may need to be ad-
justed. The high pressure can not be increased further.
Setting new limit values in the BEST Software:
• Enter new limit values via CONFIGURATION, window
PROTECTIVE FUNCTIONS, in the lines HIGH PRESSURE
SWITCH: VALUE and LOW PRESSURE SWITCH: VALUE.
8.2.3 Selecting the motor start function
The compressor control module controls the activation
and deactivation times of the motor contactors. In the
state of delivery, the time relay control is configured for
a star-delta motor. The BEST Software can be used to
switch to part winding or direct on line start. When op-
erating with frequency inverter or soft starter, the sys-
tem must also be set to direct on line start.
Adjustment in the BEST Software:
• Set the suitable motor start function in the MOTOR
STARTER FUNCTION window of the MAIN SETUP menu.
The compressors starts 1second after the release sig-
nal of the superior system controller, in any case.
8.3 Data log
All monitored operating parameters and alarm mes-
sages are recorded internally:
• All operating parameters in 10-second intervals of at
least the last 14 days
• The last 10 faults in detail
• Statistics for the last 365 days
These data can be exported as files using the BEST
Software. They enable an analysis of the system oper-
ation and detailed error diagnostics if necessary.
