3.8 OPERATOR TROUBLESHOOTING
If the unit does not behave as expected, refer to the following procedure for problems that can
be corrected without referring the unit for repair. Refer to Figure 2-2 for power-up switch loac-
tions.
1. Immediately after power-up, if the unit beeps in groups of two, power-up switch S2 is incor-
rectly set up. If the unit beeps in groups of three, power-up switch S3 is improperly setup. If
it is beeping on and off, power-up switch S1 is incorrectly set up. Verify that power up-
switches are set to the proper configuration. If necessary, turn unit off, reset switches and
turn power on again.
2. Verify all connections are properly wired and connections are tight.
3. If the MASTER/SLAVE LED is blinking - Is this a unit with a slave attached? if not, power off
unit and set Switch S2 to 00001 (S2-1 to on, all the rest off). Power up unit.
4. Verify that saved parameter(s) are not overriding the power-up switches by sending queries
for each power-up parameter to verify it is set to the configuration indicated by the power-up
switches. (NOTE: It is recommended that parameters saved using MEM:UPD be noted on
the unit to avoid unexpected behavior.)
a. If querying the power-up parameters is not possible or not easily performed, reset the lim-
its by first recording the current power-up switch settings, then performing a reset power-
up per PAR. 3.3.2.1.
b. After the unit powers up and the POWER/FAULT/LIMIT light is green and the unit is beep-
ing equally, on and off, turn the unit off.
c. Return switches to previously recorded positions from step 4a above and perform a nor-
mal power-up per PAR. 3.3.2.2.
