2.D. Following the STARTING DELAY phase 4 starting cycles of 5 seconds each start, split up by pauses of 5 seconds (these may
be programmed).
2.E. At the end of the start cycles if the gen-set has not started, there is the FAILED START signalling, if the gen-set starts but it
doesn’t reach the speed values, after 120” there will be the min voltage or frequency alarm.
2.F. With the motor running at a steady state the voltage output by the generator is read. When this is within the established
parameters the generator delay timer is triggered (this may be adjusted from 1 sec. to 30 min. approx.). At the end of this
timing the generator (CG) contact maker is closed on.
2.G. By means of a normal VDO probe for reading the motor temperature the minimum temperature beyond which the load output
is enabled can be programmed. This is to prevent operating at a low temperature in the case of the failure or failed pre-heating
of the motor.
2.H. While the generator is running two pre-alarm safety devices are enabled, oil pressure and motor temperature. When these trip
a buzzer sounds. The following safety devices and indications, when tripped, are displayed and trigger the programmable
functions described:
