OPSP This function allows for the setting of
the opening speed of the
actuator/valve. The range is 1 thru 5.
Setting 5 is the fastest opening
speed and setting 1 is the slowest
opening speed.
CLSP This function allows for the setting of
the closing speed of the
actuator/valve. The range is 1 thru 5.
Setting 5 is the fastest closing speed
and setting 1 is the slowest closing
speed.
EDb This feature configures the positioner’s operating dead-band. The configuration
options are “off” and “on”. The positioner is factory set as “off”. When the
dead-band feature is “off” it operates with nominal value of ± 0.3% of full scale
for dead-band. When the feature is turned “on”, the dead-band can be set
using the up and down arrow buttons to a value from 1 to 20. The value 1
(lowest dead-band when turned “on”) has a dead-band range of 1%, which
is equivalent to a dead-band of ± 0.5%. The value 20 (highest dead-band
value) has a range of 20%, which is equivalent to a dead-band of ± 10%.
LCD This feature configures LCD menu timeout. The range is 1 to 60 minutes. It
measures the amount of time there is no activity on the keypad and returns the
system to the main screen after the configured timeout. The default value is 10
minutes.
Adjs This function allows for the adjustment of the positioner to any position via the
keypad. This function places the positioner in digital control mode (input
current independent) and therefore allows override of the control signal.
Within this function there are Fast and Slow move modes. In Fast move mode
the valve is opened or closed in 5% increments via the keypad. In Slow move
mode the valve is opened or closed slowly via the keypad.
OP This function sets the valve to the fully energized position via the keypad
(Outlet Port 1 = Supply psi & Outlet Port 2 = 0 psi). This function places the
positioner in digital control mode (input current independent) and therefore
allows override of the control signal.
CLs This function sets the valve to the fully de-energized position via the keypad
(Outlet Port 1 = 0 psi & Outlet Port 2 = Supply psi). This function places the
positioner in digital control mode (input current independent) and therefore
allows override of the control signal.
