Rework Procedure
1. Isolate the generator set before commencing any work on the unit, open generator set breaker, activate Emergency Stop, disconnect the battery cables and either disconnect or open the control circuit breaker for the AC power supply to the battery charger. Ensure all health and safety requirements are adhered to at all times. Also, ensure proper Lock Out-Tag Out procedures are followed at all times while work is being performed on the machine. Lock out generator operation and disconnect/lockout all power sources before commencing any work.
2. Locate the pump and heater breakers inside of the dosing cabinet. A 301-8313 Terminal Block will need to added and replace the existing 301-8312 Terminal Block. Refer to Image 1.2.1.
