PULSAR MEASUREMENT
103
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.
