Manual Control Confirm that the select switches on No. which. HEEM-2 system(2 stand-by start) 1-1.1) is running. Sequential Start If power to the auxiliaries motors is restored after it was lost (blackout). the motor of the auxiliary in low pressure trouble will be automatically stopped. the previously operating motors will be started one after another according to the timing preset on their respective sequential start timers. Pushing the "START" button(3C) next energizes the starting relay(4). This abnormal stop signal is reset when the motor is re-started or the "STOP" button is pushed after the trouble is cleared. the abnormal stop signal is not produced. (b) Blackout Should a blackout occur when the motor (No.1 auxiliary is manually controlled from its starter. The following describes. At the same time. 1-1-1 Start and Running Closing the power source circuit breaker(52) or switch(89) turns on the power indicator lamp(LP). In this system. The running contactor(88) thus drops out and stops the motor. the case where the motor of No. The pressure build-up timer inhibits the stand-by auxiliary's motor from starting due to chattering of the pressure switch or on low pressure during the starting period of the other auxiliary. the stand-by motor is started instead of the running motor. Since the relay 4 self-holding. 1. the stand-by auxiliary's motor is automatically started.MOTOR AUTOMATIC CONTROL SYSTEM HEEM-SERIES SYSTEM STRUCTURE & FUNCTION The HEEM system is applied to the automatic change-over system. as an example. releasing the "START" button(3C) does not stop the motor. 1-1-3 Abnormal Stop (a) Overload Operation of the thermal overload relay(51) de-energizes the starting relay(4). These timers have each a 10-position switch for coarse time setting and a trimmer for fine time setting to cover a wide range of time setting from 00 to 100 seconds. the abnormal stop signal is produced. the starting relay(4) and running contactor(88) will drop out and the motor will be stopped. After their parallel running period preset on the parallel running timer. which then de-energizes the starting relay(4). 1-1-2 Stop Pushing the "STOP" button(3-O) energizes the stop relay(5). 2 or 3 motor starters are monitored and communicate with each other. When the motor is stopped by pushing the "STOP" button(3-O).1 auxiliary starts.2 starters are set to the "MANU" position.

After the started No.1 is pushed to reset the abnormal stop signal. When the parallel running timer for No. This also puts No. When the main power is restored and the sequential start timer counts up the set time. When No.2 abnormal stop signals are reset. the "STOP" button for No. then HEEM-2 module for No.1 will immediately relay this abnormal stop condition to No. Sequential Start Should a blackout occur when No. First. The running machine is unaffected by these switch operations but continues to run as it was.2) will be automatically reset. the "STOP" button for No. The following describes. NOTE : If you want to change from the manual mode with one of the auxiliaries in operation to the autochange mode. 1-2. though it is not operating.2 into a stand-by condition and HEEM-2 module for No.1 auxiliary is started.2 will be automatically started and run in parallel with No.1 and No. No.1 auxiliary will be re-started and the abnormal stop signal (both No. and the motor of No.2 is in stand-by condition as mentioned in 6-2 above. The output contact of HEEM-2 module for No.1 is stopped.2 has established the required pressure and the pressure switch(PS) turns off.2 is a stand-by machine. a) Abnormal Stop (due to overload or loss of control power) If the running No. where as the other machine is automatically put into a stand-by condition.
