E) Zero Lock on/off
Purpose: To activate or deactivate the zero lock feature. This feature will establish and main-
tain a zero output voltage even if the sensor detects 0-10% signal level. An invalid output sig-
nal may occur due to metallic dust accumulation within the sensor. Suppress invalid output
signals by turning on the zero lock.
Function:
Zero Lock on:
PA-24 NOT enabled and sensor signal is <10%: the output signal will be
0.0Vdc.
PA-24
ENABLED: output signal is normal (i.e. no influence on output signal).
Zero Lock off:
PA-24 NOT ENABLED: No effect on output signal.
PA-24 ENABLED: No effect on output signal.
F) External Table Select
Purpose: to activate or deactivate the remote table selection function (this requires extra ca-
ble for RTA remote table access)
Function: to turn the function on or off, select “F”.
Enabled: The valve will check for voltage at the binary inputs and select the proper table
to load. If there is no voltage detected or no cable present, the valve uses the last pro-
grammed table. Please see the datasheet or manual for more info on binary inputs.
Disabled: Will disable this feature on the valve and the table will have to be selected using
default table #1 or this program for any other table.
G) Enable Terminal While Running
Purpose: When this is on and the PA-24 cable is plugged into the valve, start the program by
simply hitting a key. There is no need to push the button on the cable. The Windows Terminal
program must be running for this to work. When this function is off use the button on the cable
must be used to start the terminal program.
