Door Locking Error Codes

A022, A023, A024, E020 & E021

When the door motor is in the open position the lower micro switch is activated and should read open and

the roller micro switch is deactivated and should read closed.

Bravo Error A022

Locking Problem

(Both door motor switches activated)

Failure of the micro switches (OFF-OFF), during the initial self test the two micro switches are ON.

Reset door motor and test door motor.

Check fuse F4 (1.25A 250V) on Gam PCB.

Check door micro switches and wiring.

Reset red button on Troll PCB

Bravo Error A023

Locking Problem

(Door motor between switches, neither switch is activated)

Failure of the micro switches (ON-ON), during the initial self test the two micro switches are OFF.

Blackout during opening

Reset door motor and test door motor.

Check fuse F4 (1.25A 250V) on Gam PCB.

Check door micro switches and wiring.

Reset red button on Troll PCB

Bravo Error A024

Locking Problem

(Door in closed position)

Failure of micro switches (ON-OFF), during the initial self test the closing micro switch is ON and the opening

micro switch is OFF. Sterilizer turned OFF before completing the safety procedure.

Reset door motor and test door motor.

Check fuse F4 (1.25A 20V) on Gam PCB.

Check door micro switches and wiring.

Reset red button on Troll PCB

Bravo Error E020

Door Unlocked

When a cycle was started the door exceeded the timeout for the operation of the door locking mechanism

(closing) 2.5 seconds.

Go to the Service menu (service code ++ -- ++ --), device test, manual, locking device. Select the locking device

then activate the door motor and check if the door hook is closing and opening. If the door motor does not

operate check fuse F4 on the Bravo Gam PCB and check the red reset button on the Troll PCB. Check the

Pressure Switch you should have continuity between the two white wires.

Bravo Error E021

Door Locked

At the end of the cycle the door exceeded the timeout for the operation of the door locking mechanism

(opening) 2.5 seconds.

Go to the Service menu (service code ++ -- ++ --), device test, manual, locking device. Select the locking device

then activate the door motor and check if the door hook is closing and opening. If the door motor does not

operate check fuse F4 on the Bravo Gam PCB and check the red reset button on the Troll PCB. Check the

Pressure Switch you should have continuity between the two white wires.

has been triggered, there is no more beeping sound when pressing the keypad remove the cover and reset the

red button on the PCB.

Bravo Door Motor Troubleshooting

The Bravo Door Motor is a DC motor. The voltage to the motor should read 24 -29 VDC. If replacing the door

motor the white wire must be connected to the terminal with the red or blue dot to the left of the label.

If there is no voltage to the door motor bypass the pressure switch. Remove the two white wires and connect

them together. If you now have voltage to the door motor the pressure switch is defective.

Comments

Door Roller Switch

43300080000

The roller switch has normally closed contacts that will open when the switch is

activated.

Door Closing Hook

(upper hook)

C0BP0590000

This hook (upper) locks the door closed and activates the door roller switch when

the door motor is in the closed position.

Door Closing Hook

(lower hook)

C0BP0590000

This hook (lower) locks the door closed and activates the door open hook switch

when the door motor is in the open position.

Door Switch

43300010000

The door switch has normally open contacts and will close when the door is

manually pushed closed.

Door Position Pin

251000003K0

When manually closing door if door does not stay closed or is too hard to close

check door position adjustment.

Door Motor Shaft

Top of door motor shaft. If door motor will not function (no power) and door

must be opened try turning the shaft counterclockwise using a large screwdriver.

Door Hook Switch

Open

43300010000

The door hook switch open has normally closed contacts that will open when the

switch is activated.

Bravo Error E010

Door Open

When a cycle is started the door must be closed and the flashing key icon should appear on the display. If no

flashing key icon appears check the Door Microswitch, it is normally open and should be closed when the door

is closed. Manually activate the switch and see if it closes. If door switch closes when manually activated but

not when door is closed check that the switch is firmly attached to the mounting plate and has not come

loose. Adjust door switch actuator.

To access the door switch actuator adjustment, remove the 5 screws securing the door facia to the door and

remove the door facia. Loosen the door switch actuator locking nut and adjust actuator using a 3mm Allen

wrench. If the door switch actuates when the door is closed but the door is pushed back open when the door

motor closes adjust the actuator out so the door must close further for the door switch to close.
