Override
A digital input can be assigned to receive an input, which will override the
setpoints of the pumps and start them, as determined by the Override
Level (P306) and providing the level is above the Min. Override (P303),
immediately after the expiry of the Override Delay (P302). A digital input
can also be assigned to receive an input, which will override the setpoints of
the pumps and stop them immediately after the expiry of the Override
Delay (P302).
Reset
This option is only available on Digital Input 7 P391 = 5 when selected a
valid signal received on this input will Reset all Device Fail signals to the no
fault condition. When using this function, the unit will check all inputs for
such conditions so there is no requirement to assign the input to a specific
relay output. Alternatively, the +/- key has been allocated as a Hot Key,
which when pressed will give details of any Device Fail and provides
prompts to Reset any failures to the no fault condition.
Digital Input Parameters
Common Par.
These parameters are common to each of the seven digital inputs and set
specific operational criteria for particular functions.
P300 Max. Attempts
When digital inputs are used to detect device failure this parameter
determines the number of attempts that will be made before failing the
device and putting it out of service. When the number of attempts is set to
‘0’, there is no restriction on the number of starts. The digital inputs will
provide a fail signal in the normal manner and initiate any action as required,
but the device will not be put out of service. Any figure other than 0 will
determine the number of attempts that will be made to start the device
before putting it out of service until such time that the input is reset.
Set the number of attempts Min. 0, Max 99.
