Constant Speed Pump Controller Installation, Operation and Maintenance Manual

5.1
Battery
The system memory, including all user setup data, is
buffered by a 3V lithium battery while the unit is off.
When the controller begins to detect low voltage on
the battery, it will display an alarm to give the user
adequate time to replace it. If the battery is not
replaced, the user setup data may be lost when the
unit is powered down.
5.2
Signal Generator (analyzer) -
recommended
The following signal generators are recommended:
Beta calibrator Model 434 20mA signal analyzer,
Altek calibrator Model 334 4-20mA loop analyzer or
Druck USP III loop calibrator. The instruments may
be purchased from a Local Process Control
Distributor. If some other instrument is used it must
float above ground, and preferably be battery pow-
ered.
5.3
Field Repair
Typical field repairs include replacing fuses, replacing
input/output modules, and assuring connections are
correct and secure. See Table 42 for a list of spare
parts.
DANGER:
Troubleshooting live control
panels exposes personnel to hazardous
voltages. Electrical troubleshooting must only be
done by a qualified electrician. FAILURE TO
FOLLOW THESE INSTRUCTIONS WILL
RESULT IN SERIOUS PERSONAL INJURY,
DEATH, AND/OR PROPERTY DAMAGE.
