10.5Replacement Parts Instructions

DANGER

Electrical Shock Hazard

Disconnect electric before service.

Controller must be properly grounded to an electrical source.

Failure to follow these instructions can result in death or electrical shock.

10.5.1 Plug-In Relay

To replace the plug-in relay, turn off 120 V power to the relay board. Turn off the 24 V power switch on the relay board. Locate the malfunctioning relay and pull the relay from its socket.

Fit a new relay in the socket. Return 120 V power to the relay board and turn on the 24 V power switch on the relay board. Press the reset button on the control board and close the doors.

10.5.2 Control Board Power LED

The LED is linked to the 24 Vac input which supplies the control board with power. If the LED is not lit, there is no power to the board. If this is the case, check the 120 V power wiring to the relay board, the 24 Vac power wiring from the relay board to the con- trol board and the 24 V power 1 A fuse.

10.5.3 10080122 Eprom Chip

The Eprom is where the controller's program (not settings) is stored. To take out the Eprom. The following steps must be taken:

Turn off the power to the control board by turning off the 24 V power switch on the relay board.

Locate the Eprom and with a small terminal screw driver placed underneath the device, pry the Eprom out of the socket.

To fit a new Eprom, look for the notch on one end of the Eprom.There is a notch on the socket and a notch on the Eprom. The Eprom should be fit so that the notch on the socket and the Eprom are aligned.

Turn on the 24 V power switch on the relay board, press the reset button on the control board and close

the doors.

10.5.4 24V Power 1 A Fuse

To replace the 1 A fuse, turn off power to the relay board and turn off the 24 V power switch on the relay board.

Locate the 1A fuse and remove it from its socket

using a flathead screwdriver. Twist the fuse a 1/4 turn counter-clockwise until the fuse pops out of the socket. Replace it with a new fuse.

Slide the fuse back into the socket, press down and turn the fuse a 1/4 turn clockwise until secure.

Return 120 V power to the relay board and turn on the 24 V power switch on the relay board. Press the reset button on the control board and close the doors.

10.5.5 Variable Frequency Drive (VFD)

To replace the Variable Frequency Drive, turn off all power to the drive assembly at the breaker or discon- nect switch. Turn off 120 V power to the relay board inside the ROBERTS GORDON® ULTRAVAC™ Con- troller. Turn off the 24 V power switch on the relay board.

Mark all wires connected to the VFD, noting the ter- minals that they are secured to. Remove all wires from the VFD terminals.

Remove the VFD from its mounting plate by remov- ing the four securing screws.

Verify that the input voltage noted on the rating plate of the VFD matches the input voltage of the old VFD. Secure the new VFD to the mounting plate with the four screws. Return all wires to the correct VFD ter- minals. If possible, it may be easier to partially re- wire the new VFD before mounting it to the mounting plate.

Close the door and return power to the VFD. Return 120 V power to the relay board. Turn on the 24 V power switch on the relay board. Press the reset but- ton on the control board and close the doors.

10.5.6 Variable Frequency Drive 25 A or 10 A Fuse

To replace a fuse, turn off input power to the variable frequency drive assembly at the breaker or disconnect switch.

Turn off 120 V power to the relay board inside the ROBERTS GORDON® ULTRAVAC™ Controller. Turn off the 24 V power switch on the relay board.

Inside the VFD assembly, open the fuse holder by
