Doran UBM-00 Universal Exterior Light Monitor
Product Information
The Doran UBM-00 is a fully electronic Exterior Light Monitor designed for use with incandescent, halogen, Light Emitting Diode (LED) constant burn and strobing lights. It is specifically designed to work with the large differences in current draw between incandescent and LED lights. The monitor can be calibrated to work with different types and manufacturers of lights. The monitor is typically wired with no more than two (2) lights in parallel, and both lights must be of the same type and manufacturer. For example, two (2) 7 stop/tail lights or two (2) 4 stop/tail lights should be wired in parallel. However, an alternate wiring option is available for buses wired with a 7 and 4 stop/tail in parallel for the right and left sides. Calibration of the unit is necessary after installation and each lamp replacement. The monitor requires all monitored lights to be in working order for self- calibration.
Product Usage Instructions
- Install the Doran UBM-00 Exterior Light Monitor according to the provided instructions.
- Wire the unit with no more than two (2) lights in parallel, ensuring that both lights are of the same type and manufacturer. Preferred wiring options are two (2) 7 stop/tail lights or two (2) 4 stop/tail lights wired in parallel.
- If an alternate wiring option is used with a 7 and 4 stop/tail lights in parallel for the right and left sides, note that the monitor may not be able to detect a failure of only one of the paralleled lights, but it will detect a failure of both.
- After installation and each lamp replacement, calibrate the unit using the following steps:
- To ensure faster calibration, turn on as many exterior lights as possible at the start of the procedure. Activate these lights during the calibration procedure.
- When the ignition is turned on, all LEDs on the monitor will be enabled for a few seconds to verify their functionality.
- To enter the calibration mode, locate and press and hold the calibrate button through the face plate hole for longer than two (2) seconds. The button/hole is located at the bottom left corner of the bus image on the monitor faceplate. You may use an object such as an allen wrench or paper clip to activate the switch.
- The first light to calibrate will begin flashing when the unit enters calibration mode.
- Repeat the calibration process for all monitored lights.
Monitor and Light Installation
The Doran UBM-00 is a fully electronic Exterior Light Monitors designed for use with incandescent, halogen, Light Emitting Diode (LED) constant burn and strobing lights. In order to work with the large differences in current draw between the incandescent versus the LED lights, it is necessary to “calibrate” the monitor for the lights installed.
- Preferred Wiring — Wire the unit with no more than two (2) lights in parallel and both lights must be of same type and manufacturer. Typically, the two (2) 7” stop/tail lights should be wired in parallel and the two (2) 4” stop/tail lights should be wired in parallel.
- Alternate Wiring — Sometimes buses are wired with a 7” and 4” stop/tail in parallel for the right and left sides. If wired in this manner, the monitor may be unable to detect a failure of only one of the paralleled lights, but it will detect a failure of both.
Calibrate unit after installation and after each lamp replacement.
Calibration
To self calibrate the monitor, ALL monitored lights must be in working order.
For faster calibration, the operator may turn on as many exterior lights as
possible at the start of the procedure. The operator will be required to
activate these lights during the calibration procedure. Operator may begin
with the tail/head lights on, hazard lights (for the turn signals), and the
amber warning lights flashing (door closed).
- Turn on ignition and start engine – Engine is running to assure proper voltage for operation and calibration. The GREEN LED voltage indicator at the bottom center of the monitor MUST BE ILLUMINATED indicating the voltage is within limits for proper operation. Before beginning calibration, allow time for the voltage to stabilize to its normal running voltage. After cranking the engine the battery voltage may be lower than normal. Allow time for the battery to recharge.
- When the ignition is turned on, all LED’s on monitor will be enabled for a few seconds to verify that all LED’s are working.
- To enter the calibration mode, press and hold the calibrate button through the face plate hole for longer than two (2) seconds. This button/hole may be found located at the bottom left corner of the bus image on the monitor face plate. The first light to calibrate will begin flashing when the unit enters calibration mode. You may use an object such as an allen wrench or paper clip to activate the switch.
- The unit will begin calibrating each light in a sequence. Each light tested must be active at the time of the calibration. As each light is calibrated, the matching monitor LED will flash. Operator shall activate (if not active) the bus light corresponding to the flashing LED. The sequence is as follows:
- a. Left turn signal – switch on
- b. Right turn signal – switch on
- c. Stop lights (left, then right side 7” will flash) – press brake pedal
- d. Tail light (left, then right side 4” will flash) – switch on (brakes off)
- e. Backup lights – press brake/clutch and engage reverse
- f. Each Amber warning light – switch on with door closed
- g. Each Red warning light – open door
- Calibrated lights are indicated by the corresponding LED staying illuminated on the monitor. The unit continues to loop through the sequence flashing the un-calibrated lights until all lights are calibrated.
- When all LED’s are illuminated, turn off ignition to complete the calibration.
Operation
The GREEN LED at the bottom center of the monitor MUST BE ILLUMINATED
indicating the voltage is within limits for proper operation. With the GREEN
LED on, a lighted LED on the monitor display indicates the corresponding bus
lamp/light circuit is drawing current. If the monitor LED does not illuminate
when the corresponding bus light should be active, this/these bus lights
should be checked for proper operation.
See the illustrations for the definition of the brake/stop and tail light
indicators.
