Friction Low
Alarm
Indicates the friction has passed
below the user set limit. The alarm
indicates a more severe condition
than the warning.
Check for a packing leak. Tighten or
replace the valve packing.

Valve Cycles
Limit Alert
Indicates that the cycle limit has
been exceeded. The cycle counting
criterion and count limit are set by
the user to track the usage of the
valve.
Follow routine procedures for mainte-
nance when the limit is reached such
as checking the packing tightness,
and checking the linkages for wear,
misalignment, and tightness. After
maintenance, reset the cycle ac-
cumulator.

Valve Travel
Limit Alert
Indicates that the total accumulated
travel limit has been exceeded. The
cycle counting criterion and count
limit are set by the user to track the
usage of the valve.
Follow routine procedures for
maintenance when the limit is
reached such as checking the packing
tightness, and checking linkages for
wear, misalignment and tightness.
After maintenance reset the travel
accumulator.

High Warning
Indicates the internal electronics
have exceeded the user set limit.
The maximum limit of the electron-
ics and default setting is 185

life of the positioner.
Regulate the temperature of the posi-
tioner. If the temperature reading is in
error, replace the main board.
