Troubleshooting Bulk Tank Full Message on OXE 100

Overview

Why is the TANK FULL message displaying?

Some bulk oil suppliers have Discard Tank Full (DTF) signal to warn the fryer when the discard tank is full. The dispose system hardware and supplier determine the method the bulk supply hardware uses to interact with the fryer.

Discard Tank Full signal displays in the following three situations:

1. DTF signal is not provided.

   The bulk dispose system might not supply a DTF signal at all. In this case, select the “NONE” option. The control will completely ignore the DTF input, and will allow pumping whether there is voltage there or not.

2. DTF signal is provided, and the presence of voltage on the DTF wires means “the tank is full, do not pump”.

   RTI bulk dispose systems typically use the “24V=FULL” option. When the discard tank is full, a 24 VAC signal is sent to the fryer. When the tank is not full, no voltage is sent.

   If the tank is full, but the DTF cable is not plugged in, the fryer sees no voltage at the DTF input, and will pump to the discard tank.

3. DTF signal is provided, and the presence of voltage on the DTF wires means “ok to pump, the tank is not full”. (Frontline International logic.)

   Frontline bulk dispose systems typically use the “24V=OK” option. When the tank is not full, 12 VDC is sent to the fryer signaling it is okay to pump oil. If the tank is full, the bulk supply system is not connected to the fryer, or the bulk oil system is not connected to power, no voltage is sent on the DTF wires, and the fryer will not pump oil to the discard tank.

Procedures

1. Press and hold the menu button until *MAIN* displays.

2. Press the menu button again.

3. Select 4. PROG.

4. Enter 123. The 3. SPCL PROG menu displays.

5. Select 3. SPCL PROG. The Special Program menu displays.

6. Use the left or right arrow to navigate to SP-17. The SP-17a setting offers three options: “NONE”, “24V=FULL” and “24V=OK”.

7. Choose one of the three options based on the situation:

   • If DTF signal is not provided: Select “NONE”.

   • If DTF signal is provided, and voltage on the DTF wires means “the tank is full, do not pump”: Select “24V=FULL” (even if signal is only 12v).

   • If DTF signal is provided, and voltage on the DTF wires means “ok to pump, the tank is not full”: Select “24V=OK” (even if signal is only 12v).

Once the DTF options have been set, press and hold the Menu button to exit out of Special Program mode.
