P*301 Switch Mode
When an external duty switch is used this can be connected via the digital
inputs and facilitate the selection of the duty device manually, thereby
overriding the duty programmed within the unit.
This parameter determines the type of switch in use.
A standard switch, e.g. rotary switch, can
be used with one switch position and a
digital input required for each pump.
To reduce the number of digital inputs
used, for manual duty selection, a binary
switch can be supplied. Max. No. of digital
inputs required being three.
P*302 Override Delay
A digital input can be assigned to receive an input, which will override the
setpoints of the pumps and start them, providing the level is above the Min.
Override (P*303), immediately after the expiry of the Override Delay.
Enter the required delay time in minutes. Default = 0.0 feet.
P*303 Min Override
Determines the minimum level required before an Override Delay (P*302)
will be in effect.
Enter the required level in Measurement Units (P*104).
Default = 0.0 feet.
P*304 Input Delay
This parameter determines the delay applied, from the time a device (relay)
is called to “run” and when the status of the digital input is recognised as a
valid input. If the digital input is used to detect a “running” signal this
parameter should be set to reflect the time it takes from the device being
called to “run” to the input being in its operational status.
Enter the required delay time in seconds. Default = 10 seconds.
