5. Start-Up/Operation - Operating the Local Display at High Temperatures
Revision 5 10260S HercuLine® Actuator Installation, Operation and Maintenance Manual 75

Operating the Local Display at High Temperatures
The temperature limits for the actuator local display are listed as -30
°
C to +50
°
C (-20
°
F to +122
°
F). The
display is programmed to shut off automatically at operating temperatures above +50
°
C.
At high temperatures, pressing the DISPLAY or SETUP keys will turn on the display. The display will
remain on and then shut off again after 4 minutes if no keypad activity is detected and the temperature is
still above +47
°
C.
Operating Displays
Pressing the DISPLAY key cycles the display through a number of operating parameters. Table 29 shows a
number of sample displays that can be shown during operation.

Display Description
0.0
INP
Input — Upper Display = Shows input value
Lower Display = prompt
00
OP 0.5
Output — Upper Display = Shows input value
Lower Display = Shows output value
100.0
DE 99.9
Deviation — Upper Display = Shows input value
Lower Display = Shows value of deviation of
sensor from input.
0.6
POS
Position — Upper Display = Shows value of position sensor.
Lower Display = prompt
NOTE: Position display will show negative values, if appropriate.
NOTE: When the AUTO/MANUAL key is pressed, placing the actuator in manual mode, the Position
display (POS) becomes the current local display.
Motor Stall
The actuator is equipped with a low current motor that prevents against burnout if the motor becomes
stalled. A stall condition occurs when the motor position does not follow the input, or if the motor does not
reach setpoint within a given period of time. The actuator sets the STALLED LED indicator on, along with
any other alarms or relay contacts that are programmed to close when a stall condition is detected. The
maintenance statistic for accumulated stall time is incremented.
A stall condition is not detected if a limit switch is set while the motor is moving toward setpoint, or if the
motor position is within 0.5 % of setpoint.
