Service

5. Service

5.1. Maintenance

The maintenance menu contains information about running hours and operation time since
last start.

5.1.1 Service timers

Hour counter
Shows the total number of compressor operating hours.
Since start
Shows for how long the compressor has been running since it was last started. When stopping
the compressor, the counter stays on the value reached at that particular moment. This way
it can be seen how long the compressor has been running since the last operating period.
When the compressor is restarted, the counter restarts from 0.

5.1.2 Maintenance compressor (screw and reciprocating)

Static compressor service information is available for the following screw and reciprocating
compressors.
• Screw compressors type SAB 120, 151 and SAB 193, 233, 283, 355
• Screw compressors type SAB 157HR and SABflex
• Screw compressors type SAB 128, SAB 163 and SAB 80
• Reciprocating compressors type SMC Mk4 and CMO
Dynamic Service on Demand functionality, i.e. Automatic service interval calculation depend-
ing on the compressor running conditions, is available for the following screw and reciprocat-
ing compressors:
• Screw compressors type SAB 120, 151 and SAB 193, 233, 283, 355
• Screw compressors type SAB 157HR and SABflex
• Screw compressors type SABCube 109, 133 and 159
• Reciprocating compressors type SMC Mk4 and CMO
The intention with the Service on Demand module is to optimise the length between service
intervals. The optimisation is found by combining the knowledge of the actual compressor op-
eration based on Unisab III data supervision combined with advanced calculations based on
maintenance algorithms.
