NOTE
SW1 position 3 and 4 must be in their Up position for operation
with 4-20mA Isolated Programming and Monitoring.
CAUTION
To prevent damage to the unit, do not program the output voltage and current
to higher then the power supply rating.
Perform the following procedure to configure the power supply:
1. Turn the power supply AC power switch to Off.
2. Connect a short between J1-8 and J1-12 (refer to Table 4-4).
3. Set Setup switch SW1-1 to its UP position for Output Voltage external programming
and SW1-2 to its UP position for Output Current limit external programming.
4. Set SW1 position 3 to select the programming voltage range: Down=0-5V, Up=0-10V.
5. Set SW1 position 4 to select the monitoring range: Down=0-5V, Up=0-10V.
6. Ensure that SW1 positions 7 and 8 are in the their down position.
7. Connect the programming sources to the mating plug of the Isolated Programming
connector. Observe for correct polarity of the voltage source.
8. Set the programming sources to the desired levels and turn the power supply ON.

9.1 INTRODUCTION
9.2 UNITS UNDER WARRANTY
9.3 PERIODIC MAINTENANCE
9.4 ADJUSTMENTS AND CALIBRATION
9.5 PARTS REPLACEMENT AND REPAIRS
This chapter provides information about maintenance, calibration and troubleshooting.
Units requiring repair during the warranty period should be returned to a Lambda authorized service
facility. Refer to the addresses listing on the back cover of this manual. Unauthorized repairs
performed by other than the authorized service facilities may void the warranty.
No routine maintenance of the power supply is required except for periodic cleaning. To clean,
disconnect the unit from the AC supply and allow 30sec. for discharging internal voltage. The front
panel and the metal surfaces should be cleaned using mild solution of detergent and water. The
solution should be applied onto a soft cloth, and not directly to the surface of the unit. Do not use
aromatic hydrocarbons or chlorinated solvents for cleaning. Use low pressure compressed air to
blow dust from the unit.
No internal adjustment or calibration is required. There is NO REASON to open the power supply
cover.
As repairs are made only by the manufacturer or by authorized service facilities, no parts
replacement information is provided in the manual. In case of failure, unusual or erratic operation of
the unit, contact a Lambda sales or service facility nearest you. Please refer to the Lambda sales
offices addresses listing on the back cover of this user manual.
If the power supply appears to operating improperly, use the troubleshooting guide to determine
whether the power supply, load or external control circuit are the cause.
Configure the power supply for basic front panel operation and perform the tests of section 3.8 to
determine if the problem is with the supply.
Table 9-1 provides the basic checks that can be performed to diagnose problems, and references to
sections of this manual for further information.
9.6 TROUBLESHOOTING
