Contactor is
being held
open due to
auto reclose
limit being
reached.
An internal contactor automatic reclose event is pending but the contactor is
being held open because the number of re-close attempts in a set time has
been exceeded.
The PQconnect continuously monitors the internal conditions of the HGL
filter and the external conditions of the filter line and load currents and
voltages. Some status conditions are configured to open the tuned circuit
contactor when detected as a self-protection feature. An optional feature can
be enabled (feedback parameter 252) to attempt to re-close the tuned circuit
contactor after a status condition has been detected. However, if too many
re-close attempts (parameter 282) are made within a set time (parameter
283) the unit will stop attempting to auto reclose.
To debug which status conditions caused the contactor open event the
presently configured contactor open actions can be audited using feedback
parameters 240-Filter A, 241-Filter B 242-Filter Line and 243 Filter Load.
The set or clear status of these contactor open status detections can be
viewed via feedback parameters 210-Filter A, 211-Filter B 212-Filter Line
and 213 Filter Load. Also, the present value of all status detections and
wither they are configured to open the tune circuit contactor when detected
can be viewed via the PQvision software settings menu screen.
When the auto re-close limit has been reached a power cycle of the filter unit
is required to clear the condition and allow the contactor to re-close.
Warning
Many electronic components located within the filter are sensitive to static electricity.
Voltages imperceptible to human touch can reduce the life, affect performance and/or
destroy sensitive electronic devices. Use proper electrostatic discharge (ESD)
procedures when servicing the filter and its circuit boards.
