Zener 8000 Application Manual page 15

Application SW08024: PID Irrigator
Remaining Parameters:
The remaining parameters to implement & adjust if required are:
Pipe Fill:
The pipe fill option allows the ZENER 8000 to operate at a reduced speed to fill the pipes on start. Pipe
fill is only activated when a start/run command is first given.
Pipe Fill
Pipe Fill Speed (Hz)
Pipe Fill Level
Pipe Fill time (s)
Bore Level Timeout:
Low Bore timeout
Note:
1. If no 'Bore Level switch' is installed fit a bridging link between terminal 1 and 37.
2. If operated with a start/stop switch the low bore switch will stop the pump and not allow a restart until
the time-out period has lapsed.
Variations & Other Adjustments:
Other parameters may need to be adjusted because:

The setup may vary from the intended application Eg. Use different set point source/reference such as
a potentiometer.

Additional requirements which the application does not include. Eg. An additional alarm for over
current.
Parameters that you may want adjustment include:
Change Ramp Times:
Ramp types: C030 Accel Time & C031 Decel time = ramp time above minimum speed
C032 S-time = ramp time to minimum speed
ESC to Menu> <DOWN>>> C00 PERFORMANCE <ENTER><DOWN>>>C03 RAMP<ENTER to edit><UP/DOWN to select ramp
type>>and<ENTER to save><ESC> ('ramp time' is time taken from 0 to 50Hz)
Note: The time entered is the time from 0 – B03 MOTOR Hz.

DISABLED To Enable, set to 'PV Threshold'.
changeover to PID when a pressure level is reached.
40 Adjust the speed to operate during pipe fill mode
80 psi Adjust the level to switch from 'Pipe Fill Mode' to 'PID mode'
40 Adjust to the time required to reach the 'Pipe Fill Level' pressure.
0 Enter a time period to restart after a 'Low Bore' is detected or
install link if a 'Bore level switch' is not installed.
This feature requires a bore level switch to be installed.
When an 'open contact' is present on input D4( terminal 37) the
ZENER 8000 stops and displays the warning '–DRY-'. When the
contact closes there is a delay before the pump restarts.
