The decision on whether or not to attempt to start the failed pump on
subsequent pump cycles will be determined by
P300 Max. Attempts . Once
the number of attempts stipulated have been made the pump will be put out
of service until such time the Device Fail input is cleared by a
Reset ( P391 =
4) on Digital Input 7. Alternatively the key can be used as a as a Hot Key,
which when pressed, whilst the unit is in RUN, will give details of any Device
Fail and provides prompts to Reset any failures to the no fault condition.
Duty
When this function is selected the digital inputs are used to determine, via an
‘auto/manual’ switch,
which one of the devices, connected to the relay outputs
of the Quantum
3
, will be the “lead” or “duty” device.
Consider the example of an application using 2 pumps. Each pump is
connected and controlled by one of the Quantum
3
relay outputs, the pump
duty and setpoints have been programmed as detailed in Using the Relays ,
earlier in this chapter. The signals providing details on the “lead” or “duty”
pump ‘status’ are connected to the digital inputs as described in
Chapter 2
Installation , and the input Type P372, 375, 378, 381, 384, 387, 390 is
configured as detailed in Input Type , earlier in this chapter.
Pump 1 is connected and programmed to operate on Relay 1
Pump 2 is connected and programmed to operate on Relay 2
Pump 1 Duty signal is connected to Digital Input 3
Pump 2 Duty signal is connected to Digital Input 4
The type of switch to be used to determine the duty is selected and configured
as detailed in
P301 Switch Mode .
Standard Switch Mode (P301 = 0 Standard)
When a standard rotary type switch is used, to determine auto/manual duty
one input per device is required, with each input being assigned to the
appropriate device relay output that it relates to, this is determined by
Assignment P374, 377, 380, 383, 386, 389, 392. In the case of our example
Digital Input 3 will be assigned to Relay 1 (P380 = 1) and Digital Input 4
will be assigned to Relay 2 (P383 = 2) .
