ASTAT ® -CD Plus Soft Starters
WARNINGS
1. Disconnect power before installing or servicing.
2. Hazardous voltages are present in the motor circuit even when the starter is OFF. An
isolation contactor configured to provide automatic isolation when the motor is turned
OFF is recommended.
3. Unit may contain more than one live circuit. Disconnect both control and main circuits
before installing or servicing.
4. Soft stop should not be used as an Emergency stop.
5. Stopping mode must be set to meet applicable standards for operator safety.
6. Separate motor overcurrent protection is required to be provided in accordance with the
Canadian Electrical Code, Part 1. ASTAT-CD Plus provides separate motor protection.
CAUTIONS
1. Semi-conductor fuses specified may not provide branch circuit protection. Refer to local
applicable electrical codes.
2. Overload relay setting should be properly coordinated with motor.
3. Slow speed running will affect the motor thermal characteristic due to reduced cooling.
Care must be taken when operating motor under these conditions.
4 DC braking - braking current may cause motor overheating. Select the lowest braking
current and time.
5. DC braking must use additional (DC3) in the motor circuit. See wiring diagram page 6-1.
6. Abnormal starting times in excess of 30 seconds, or closely repeated operations of
acceleration ramp/deceleration ramp, slow speed, or DC injection braking may cause
motor damage. Contact motor manufacturer to ensure proper motor selection has been
made for these conditions.
7. If control power is lost between starts, the overload relay protection is reset to cold start
conditions.
