Table 14 Relay Type Descriptions
When this Relay Type is
selected…
(RTYP)
The Relay can be set up to indicate …
Input Range
The upper / lower limits of the input signal have been exceeded.
Relay value parameter defines range limits and units are in percent of full span.
Position Range
Upper / lower limits of motor position have been exceeded.
Relay value parameter defines range limits and units are in either percent of
span or degrees of rotation. See “Relay Examples “for setting range limits.
Deviation
Motor position has exceeded deviation limit from input. (Deviation is defined as:
setpoint – motor position = Deviation)
Relay value parameter defines limits and units are in percent of span.
See “Relay Examples” for setting deviation limit.
Upper Limit Travel
The motor position has exceeded the upper limit of travel.
(Same as Position Range.)
Relay value parameter defines limits and units are in degrees of rotation or
percent of span. See “Relay Examples” for setting upper limit with hysteresis.
Lower Limit Travel
The motor position has exceeded the lower limit of travel.
(Same as Position Range.)
Relay value parameter defines limits and units are in degrees of rotation or
percent of span.
Temperature High
The high temperature limit of the actuator has been exceeded. Relay value
parameter defines temperature limits and units are in either degrees C or
degrees F.
(Temperature units are defined in the UNITS setting of the DISPLA set up
group.)
Temperature Low
The low temperature limit of the actuator has been exceeded. Relay value
parameter defines temperature limits and units are in either degrees C or
degrees F.
(Temperature units are defined in the UNITS setting of the DISPLA set up
group.)
Starts
The accumulated motor starts have exceeded the limit. Relay value parameter
defines the limit. See “Relay Examples” for setting motor starts limit. Range is
from 10 to 99,990,000.
Stall
The motor is in a stall condition.
Manual Mode
The actuator is in manual mode.
Power Up Test Failure
A failure of any one of the power up test diagnostics. See READ STATUS set up
group.
Failsafe
The actuator is in failsafe. (input signal loss or input signal out of valid range)
Position Sensor Failure
The potentiometer or non-contact sensor output is out of range or has failed.
Digital Input
The digital input closure.
Total Degrees
The total degrees traveled.
