rSEr 1. Check that the Remote Setpoint signal is present
Remote Setpoint Error and of the correct polarity between terminals 8 (+)
and 5 (-).
2. Perform the Auxiliary Input Test, Test 9 as
described in the Test section (page 51), the
voltage indicated during the test should be the
same as measured in the preceeding step.
3. Verify that the Remote Setpoint input voltage range
selected in the Program Mode (page 28) is the
same as the voltage that is present as the Remote
Setpoint input terminals.
FbEr 1. Inspect the Slidewire Feedback connections at
Slidewire Feedback Error terminals 8, 7, and 5. Be sure that the
connections are the same as shown in the position
proportioning illustration (page 21).
2. Measure the resistance of the Slidewire segment.
The minimum resistance must be 135 ohms, the
maximum 10 K ohms.
3. Perform the Auxiliary Input Test. Test 9 as
described in the Test section, the voltage indicated
should be between 0 and 5 VDC.
4. Turn off the power to the instrument. Loosen the
front panel screw and take the instrument out of
the housing. Verify that the jumper JU-1 on the
Option Board (Appendix A-3, page 61, 62) is in the
Motor Modulation position.
Hi - Input more than 10% 1. Perform the steps listed for the SnSr error
Over Span condition (page 54).
Lo - Input more than 10% 1. Perform the steps listed for the SnSr error
Under Span condition (page 54).
o - display overrange 1. If this error code is displayed as a Program or Tune
(the “broken 6” appears mode parameter value , perform the CAL 1
on the left side of the display) procedure as described in the Calibration
section (page 45).
2. If this error code appears as part of the model
number during the power up sequence, follow the
steps listed for the Model number incorrect
condition (page 52).
Er 1 - Microprocessor RAM 1. Turn off the power to the instrument.
Failure 2. Loosen the front panel screw and remove the
instrument from the housing. Inspect that the
microprocessor (U1) is properly seated in the
socket located on the Processor board (Appendix
A-2, page 60). Return the instrument to the
housing and tighten the front panel screw. Turn
on the power.
Er 2 - External RAM Failure 1. Turn off the power to the instrument. Wait 5
seconds, and turn the power on.
Er 3 - EPROM Checksum 1. Perform the steps listed for Er 1 except that the
Failure EPROM (U2) on the Processor board should be
inspected.
