1.1 ATO (Automatic Top-off) Service Procedures

2

The automatic top-off system is activated when the oil level falls below a sensor in the rear of the
frypot. The signal is sent to the ATO board to engage the solenoid to the frypot and turn on the
ATO pump. The pump draws oil from the JIB (Jug In Box) to a port in the rear of the frypot.
Once the oil level has satisfied the sensor, the pump and solenoid turn off.

The ATO board is located inside the box, behind the
JIB (see Figure 1). The power for the ATO board in
electric fryers is supplied from the right hand
component box. On gas fryers the power is supplied
from the transformer box in the rear of the fryer. The
power passes through the transformer inside the ATO
box to the board. On the left side of the ATO box is
a power switch, which controls the flow of power
between the component/transformer box and the
ATO board.

switch located
on the left side
of the JIB auto
top off box.

1.2 MIB (Manual Interface Board) Service Procedures

The MIB (Manual Interface Board) oversees and controls filtration. It receives and sends data
over the CAN (Controller Area Network) to and from various sensors and computers. It
activates the filtration cycle; controlling when actuators should open and close.

The MIB controller is located inside the left cabinet (see Figure 4). In normal operation a cover
hides the MIB controls and the LED display is visible. The cover is held in place with three torx
screws. In normal operation, an “A” is displayed for automatic mode. The MIB control board is

useful for diagnostic purposes. It allows manual operation of both the actuators and filter pump
without using the M2007 computer.

Manual – This button is used to toggle between auto and manual filtration mode. A
corresponding LED is lit when in Manual mode. When pressed, a message will be sent to all
vats, indicating the mode has changed.

The following buttons are inoperable in auto mode:
Select - This button is used to scroll through available vats, choosing one to be manually filtered.
Drain – This button is used to open and close the drain on the vat indicated on the display.

When the button is pressed and the manual board is waiting for a response from the AIF board,
the corresponding LED will blink slowly. Once a response is received the LED will be
illuminated if the drain is open or extinguished if the drain is closed. If a message was not
received from the AIF board, it times out and the LED will blink rapidly.

Return – This button is used to open and close the return valve on the vat indicated on the
display. It also turns on and off the pump. When the button is pressed and the manual board is
waiting for a response from the AIF board, the corresponding LED will blink slowly. Once a
response is received, the LED will be illuminated if the return is open or extinguished if the
return is closed. If a message is not received from the AIF board, it times out and the LED will
blink rapidly. The pump is turned off first before closing the return valve or the valve will open
first before turning on the pump.

1.2.1 Manually Draining, Refilling or Filtering using the MIB board

Press the manual/auto switch to set to manual.
The LED on the manual key will illuminate
and a vat number is displayed (see Figure 6).

Press the vat selector switch to change vats
(see Figure 7).

Pressing the drain or return switch illuminates
and activates the drain or return valve for the
vat indicated. Pressing both allows filtration
(see Figure 8).

Pressing the manual/auto switch will return to
automatic mode.

1.2.6 Replacing the MIB Board

Disconnect the fryer from the electrical power supply. Remove the torx screws from the MIB
cover, exposing the MIB board (see Figure 9). Removing the four nuts in the corners
disconnects the MIB board. Carefully remove the plugs on the rear of the board (see Figure 10).
Replace with a new MIB board and reverse steps to reassemble. Once replaced, reconnect the
power.

The board will need to be readdressed to the system. Readdress the fryer by pressing and
holding

3and 4 simultaneously for TEN seconds until a third chirp is heard and code

appears. Enter 2007. The MIB display will display L for several seconds followed by the vat
number alternating with “r” until the readdress is complete. When the readdress is finished, the

MIB board will display A. This step must be done when a MIB board is replaced. The
readdress procedure can be done from any one M2007 computers in the bank.

The AIF (Automatic Intermittent Filtration)
board controls the actuators that open and
close the drain and return valve. The AIF
boards are located inside a protective housing,
under each frypot (see Figure 11).

1.3.1 AIF Troubleshooting

Problem Probable Causes Corrective Action

A. Ensure the actuator is plugged

into the proper connection.

B. Check power on the connector

of the problem actuator while
trying to manually open or close
an actuator. Pins 1 (Black) and
4 (White) should read +24VDC
when trying to open an actuator.
Pins 2 (Red) and 4 (White)
should measure -24VDC when
trying to close an actuator). If
either one of these voltages are
missing, the AIF board may be
bad. Test the actuator by
plugging into another connector
to open or close the actuator. If
the actuator operates, the board
is bad. Replace the board.

C. If proper voltages are present at

the connector and actuator
doesn’t operate, actuator may be
bad. Replace the actuator.

A. Ensure the actuator is plugged

into correct connection.

B. Ensure the locator pin is in

proper position in plug J2. See

1.3.4 Replacing an AIF (Automatic Intermittent Filtration) board

18

Disconnect the fryer from the electrical power supply. Locate the AIF board to be replaced
under a frypot. Mark and unplug the harnesses. The AIF board assembly is held in place with
one screw in the front of the assembly (see Figure 12). Remove the screw and the front of the
assembly drops down (see Figure 13) and the back tab slides out of the bracket attached to the
frypot (see Figure 14). Reverse steps to reassemble, ensuring that the new AIF assembly slides
into the slot in the rear of the bracket.

Figure 12 Figure 13 Figure 14

1.3.5 Replacing an Actuator

Disconnect the fryer from the electrical power supply. Locate the actuator to be replaced under a
frypot and mark and unplug the actuator. The actuators are held in place by two clevis pins that
are held in by cotter ring pins (see Figure 15). Remove both clevis pins and remove the actuator.
Attach the new actuator with the rear clevis pin and cotter ring pin first (see Figure 16). With the
actuator attached with the rear clevis pin only, adjust the new actuator by rotating the shaft until
the holes of the actuator and valve plate are aligned. Rotating the shaft clockwise, adjusts it
outward. While rotating it counterclockwise adjusts the shaft inward. Insert the clevis pin and
the cotter ring pin to secure. If a return valve was replaced, filter a different vat of oil. If bubbles
appear in the vat where the actuator was replaced, further adjustment is necessary. Take out the
pins and adjust the valve until no bubbles are present in the vat. Reinsert the pins to secure the
actuator.

1.8 RTI Service Issues

33

1.8.1 RTI MIB Tests

Normal measurements, measured on MIB J6 8 pin connector with
everything connected.

AC voltage measurements:

Pin 1 to Pin 2 - 24 VAC.
Pin 2 to Pin 3 - 24 VAC when RTI add pump is on, 0 VAC when it is off.
Pin 4 to Pin 5 - 24 VAC when RTI waste valve is on, 0 VAC when it is off.
Pin 6 to Pin 7 - 24 VAC when RTI JIB valve is on, 0 VAC when it is off.

DC voltage measurements:

Pin 1 to Pin 8 - 0 VDC when waste tank is full, 5 VDC when it is not full.

Troubleshooting.

The valves and pump should be off while MIB is resetting, 5 seconds or so after a power on or after
pressing the reset button; if any are on during reset then the MIB board is bad or wires are shorted.

If JIB valve is not opening:

Measure when JIB valve should be opened:

1. Voltage at MIB board from Pin 1 to Pin 2, should be 24 VAC; if not then check connections from RTI
24VAC transformer and check transformer.

2. Voltage at MIB board from Pin 6 to Pin 7, should be 24 VAC; if not then MIB board is bad or wires to
JIB valve are shorted or both.

3. Voltage at JIB valve, should be 24 VAC; if not then check wiring from MIB board.

If Waste valve is not opening:

Measure when Waste valve should be opened:

1. Voltage at MIB board from Pin 1 to Pin 2, should be 24 VAC; if not then check connections from RTI
24VAC transformer and check transformer.

2. Voltage at MIB board from Pin 4 to Pin 5, should be 24 VAC; if not then MIB board is bad or wires to
Waste valve are shorted or both.

3. Voltage at Waste valve, should be 24 VAC; if not then check wiring from MIB board.

If Add pump is not operating:
Measure when Add pump should be on:

1. Voltage at MIB board from Pin 1 to Pin 2, should be 24 VAC; if not then check connections from RTI
24VAC transformer and check transformer.

2. Voltage at MIB board from Pin 2 to Pin 3, should be 24 VAC; if not then MIB board is bad or wires to
pump relay are shorted or both.

3. Voltage at Add pump relay, should be 24 VAC; if not check wiring from MIB board.
Waste full signal:
Pin 1 to Pin 8 should be 0 VDC when full, 5 VDC when not full; if no level change, then bad

connection from RTI switch or MIB board is bad.
