Sices GC315 User Manual

GC315xx and GC400xx Technical Manual 199
Warning: if the first two conditions are met, the controller will control the pump no matter what
the threshold values are. In particular, the last condition set thresholds are used even though
related operation times are set to zero (for disabling anomalies). Very important is the
thresholds setting which should be ranked by level (from down up), as follows: minimum, low,
start, stop, high. As already explained, the controller operates even if thresholds are not in this
order; all you need is the first three ones lower than the last two ones (within each of the two
groups they can be swapped, but it is not recommended).
To use this function requires:
 Make sure you have a contact level transducer.
 Configure the controller to control the pump in accordance with said transducer
(parameter P.0401=1).
 Connect at least the pump start/stop contacts respectively to two configurable inputs
of the controller.
 If connected, the minimum, low and high fuel level contacts are also used.
Warning: if the first two conditions are met, the controller will control the pump no matter what
the connected contacts are. In particular, the contacts related to the last connection are used
even though relevant operation times are set to zero (for disabling anomalies). So, please pay
attention to configuration. Last, contacts must match the following pattern:
 Minimum level contact (input with feature DIF.4211): closed if the level is below the
minimum level threshold.
 Low level contact (input with feature DIF.4212): closed if the level is below the low
level threshold.
 Startup contact (input with feature DIF.3301) closed if the level is below the pump
startup threshold.
 Stop contact (input with feature DIF.3302) closed if the level is below the pump stop
threshold.
 High level contact (input with feature DIF.4213): closed if the level is over the pump
stop threshold.
The controller assigns the actual fuel level by calculating in the order all the following
evaluations:
 If the level is lower than the pump start threshold, the controller assigns the “start”
position.
 If a low level threshold exists, and the level is lower than threshold, the controller
assigns the “low” position.
 If a minimum level threshold exists, and the level is lower than the threshold, the
controller assigns the “minimum” position.
 If the level is higher than the stop threshold, the controller assigns the “stop” position.
 If a maximum level threshold exists, and the level is higher than the threshold, the
controller assigns the “maximum” position.
 If none of the previous condition is met, the controller assigns the “hysteresis” position.
Referring to the position evaluated in the previous paragraph, the pump:
 Activates if the level is “start”, “low” or “minimum”.
