No special tools other than those normally contained in an electronic technicians
toolkit are required to service the DP140e. To check the system voltage and reset as
necessary, it is recommended that a quality digital voltmeter be used.
Adjustments
The rectifier used in the DP140e may require adjustment of the output voltage. Care
should be used if this adjustment is made. Connect the digital voltmeter to the external
battery connector and adjust the rectifier for a voltage of 54.6 Vdc on the external
battery connector.
TROUBLESHOOTING
Troubleshooting
The attached guide is intended to provide help with any problems you may run into.
Please note that this is not a complete list of problems.
Question
- We have just completed installation of the system and we have
no front
panel indicator.
Answer
- You will need to check the following:
•
Check the power cord on the left side of the unit.
•
Check the power cord at the commercial wall outlet.
•
Check the circuit breaker in the power distribution panel.
•
Using a voltmeter, check the AC voltage at the wall outlet. This voltage
should be between 92 and 132 volts AC.
Question
- We have just completed installation of the system and we have a power
problem.
There are no indicators on the equipment connected to the
power supply.
Answer
- There are several things which need to be checked.
•
First, are the front panel indicators on the power supply on? If not go to
7.1.2.
•
At the distribution module, disconnect the cable. Using a voltmeter, check
the output connector. If your voltage is 54 volts or more the power supply is
okay.
