to power the LDT. When powering more than one
VMAX on a single power supply, remember that each
unit requires approximately one watt of
power. The amount of current draw will vary based on
the input voltage used. To calculate the current draw
for a particular LDT, divide the LDT wattage by the
input voltage. For example, 1 watt divided by 24 VDC
equals 41.6mA.
If the LDT is not operating properly, the LDT’s cable
may have an open or short, or the power supply is not
supplying sufficient power. To verify this:
1. Turn the power supply off.
2. Remove the mating connector from the LDT.
3. Turn the power supply on.
4. Using a digital voltmeter, check across Power Supply
Common and customer supplied power (+VDC) on
the mating end of the cable for a level between 7 and
30 VDC.
Appendix B: Part Numbering
NOTE: LDT’s with integral cable assemblies
should be checked for proper voltage at the power
supply terminals. This cable assembly cannot be
removed from the LDTIf the reading is between 7
and 30 VDC, turn power supply off and go to step
7. If the reading is below 7 VDC, either the power
supply is not providing enough power or the LDT’s
cable possibly has a short or open. A reading of
no voltage or minimal voltage (less than 5 volts)
may be due to a short or open in the cable. If the
reading is not between 7 and 30 VDC, go to step
5. If the reading is above 30 VDC, adjust power
supply or replace.
5. Turn the power supply off.
6. Check the continuity of the individual wires of
the cable between the power supply and the
LDT. Check for continuity from one end of the
cable to the other. Also, verify that no shorts
exist between pins.
7. Reconnect the mating connector to the LDT.
