Swing panel - front side
The swing panel (Fig. 25) is accessed by opening the cover on the enclosure. Located on the swing panel are: indicator lights, relays, timers, and a circuit breaker reset.
Immediately adjacent to the swing panel is the main circuit breaker, CB1, for the feeder breaker.

“CB1” “CB1”is the main circuit breaker for the feeder breaker. The circuit breaker reset switch on the front of the starter enclosure panel is used to control the circuit breaker when the starter enclosure cover is in place.
When looking directly at “CB1”, the circuit breaker is on when the black switch is all the way up. If the circuit breaker has been tripped, the switch will be only partially up. The circuit breaker is off when the switch is down. To reset the circuit breaker, push the switch down past off, then up to on.
“IS#1”and “CR1”
“IS#2”and “CR2”
“IS#3”and “CR3”
“IS#1”is an intrinsically safe relay that works in conjunction with the high temperature relay “CR1”. If the hydraulic oil temperature exceeds 150°F, the high temperature switch will shut the pump motor down and the “HI TEMP”indicator light will be illuminated.
“IS#2”is an intrinsically safe relay that works in conjunction with the low oil relay “CR2”. If the oil in the hydraulic tank drops below the bottom of the sight glass on the side of the tank, the low oil switch will shut the pump motor down and the “LOW OIL”light will be illuminated.
“IS#3”is an intrinsically safe relay that works in conjunction with the sequence switch relay “CR3”. If the outby belt stops, the sequence switch will shutdown the pump motor and the “SEQ SW”light will be illuminated.
“IS#4”is an intrinsically safe relay that works in conjunction with the pressure switch relay “CR4”. If the hydraulic pressure exceeds 4,800 psi, the pressure switch will shutdown the pump motor and the “PRESSURE SWITCH”light will be illuminated.
“SR”is the safety relay. If the panic bar is struck, both the pump motor and the pick break motor will be shutdown and the “SAFETY RELAY” light will be illuminated.
“CR5”is the regular mode relay. When the mode switch on the front of the starter enclosure is in the “REGULAR”position, both the pump motor and the pick break motor can be energized.
“CR6”is the tram only mode relay. When the mode switch on the front of the starter enclosure is in the “TRAM ONLY”position, only the pump motor can be energized. The pick break motor will not run in “TRAM ONLY”mode.
“CB-2”is the circuit breaker on the control circuit. If the control circuit is overloaded, or if the circuit becomes grounded, “CB2”will trip. To reset the circuit breaker, press the pushbutton on the front of the starter enclosure.
“TR1”is the breaker shaft underspeed timer. If the breaker shaft slows down below the normal speed calibrated during initial machine setup for longer than three (3) seconds, the underspeed sensor will shutdown the pick break motor.
“TR2”is the override timer for the breaker shaft underspeed timer. During startup, the override timer will allow the breaker shaft to run under speed for approximately seven (7) seconds. This override is active during startup only.
“TR3”is the conveyor run time timer. The timer is activated when the pump motor pushbutton, or the start button on the infrared remote, is pushed. The conveyor will run for approximately 2 1/2 minutes. To keep the conveyor running, the operator must push the start button (on the starter enclosure cover or the infrared remote) before the 2 1/2 minutes expires. If the timer is not reset within 2 1/2 minutes, the pump motor will shutdown.

Swing panel - back side
The back side of the swing panel (Fig. 26) is accessed by removing the swing panel retaining bolt and swinging the panel out. Located on the panel are relays, a switch, and the infrared receiver board.

“IS#5”is an intrinsically safe relay that works in conjunction with the “CR7” neutral position magnetic switch relay. In order to start the machine, the primary valve bank handles must be in neutral and the guard must be in place over the levers, activating the neutral position magnetic switch.
The “IS RELAY”is an intrinsically safe relay for the panic bar (tape switch). When the panic bar is struck, the tape switch will shutdown the machine.
The infrared receiver board processes the pump motor start and stop signal from the infrared remote.

Back panel
The back panel (Fig. 27) is accessed by removing the swing panel retaining bolt located in the upper left hand corner of the swing panel and swinging the panel out. Located on the back panel are two vacuum contactors, two overload relays, and the control transformer.

“M1”if the vacuum contactor for the pick break motor.
“M2”is the vacuum contactor for the pump motor.
“OL1”is the overload relay for the pick break motor. If the pick break motor is overloaded, the relay will shutdown the motor.
“OL2”is the overload relay for the pump motor. If the pump motor is overloaded, the relay will shutdown the pump motor.
Bottom panel
The bottom panel (Fig. 28) is located in the bottom of the starter enclosure, directly under the back panel. The bottom panel is accessed by opening the swing panel.

barrier
pick break sensor control board
Pick break sensor control board Barrier
The purpose of the barrier is to act as a shield between the nonpermissible and permissible environments. The barrier limits the current and voltage to specified levels.
The pick break sensor control board is the control board for the pick break motor.
