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 (page 55). 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 65) is in the Motor
Modulation position.
Hi - Input more than 10% 1. Perform the steps listed for the SnSr error condition
Over Span (page 58).
Lo - Input more than 10% 1. Perform the steps listed for the SnSr error condition
Under Span (page 58).
o - display overranged 1. If this error code is displayed as a Program or Tune
(the "broken 6" appears mode parameter value, perform CAL1 procedure as
on the left side of the display) described in the Calibration section (page 48).
2. If this error code appears as part of the model number
during the power up sequence, follow the steps listed
for the "Model # is incorrect" condition (page 57).
3. If this error appears in the process reading and dPoS
equals 1, then it means the process is greater then
999.9.
Er1 - 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
64). Return the instrument to the housing and tighten
the front panel screw. Turn the power on.
Er2 - External RAM Failure 1. Turn off the power to the instrument. Wait 5 seconds
and turn the power on.
Er3 - EPROM Checksum 1. Perform the steps listed for Er1 except that the
Failure EPROM (U2) on the Processor board (Appendix A-2,
page 64) should be inspected.
Er4 - RTD Mismatch Error 1. Check the connections to the instrument for the RTD
Input Calibration procedure (page 50). Repeat the
RTD Input Calibration.
