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.
