Applying Power and Operation
Applying Power
•
Before applying power to the HC-DySC, make certain there are no metal
filings or any conductive debris in or on any components inside the
cabinet.
•
Verify HC-DySC voltage rating matches ac source voltage.
•
Ensure all input/output wiring including grounding has been completed
and properly tightened.
•
Verify CBA circuit breaker is in the ON position before replacing covers.
Replace all covers. Close and lock cabinet doors.
•
Put bypass switch in the “BYPASS” position.
•
Put CBI circuit breaker in the ON position.
•
Apply power from the upstream branch protection device. Power will flow
directly to the load through the bypass switch. The HC-DySC
touchscreen will become active and display “System Offline” in the upper
left corner.
•
Verify output (load) voltage is present
•
Put bypass switch in the “TEST” position. The HC-DySC system will
become energized in this mode but the load will still be powered through
the bypass switch.
•
Ensure that the touchscreen displays “OK” in the upper left corner, with a
bar above that states “Sag Prot. Bypassed.” Ensure that the voltage, current,
and frequency readings in the status display are correct.
•
If a “Critical” or “Fatal” system event appears on the touch screen (1) place
the maintenance bypass switch in BYPASS and (2) call for technical
support.
•
Put the bypass switch in the “NORMAL” position. The load is now being
protected by the HC-DySC. The display should show “OK” in the upper
left corner.
NOTICE: Cycling HC-DySC input power in the sequence OFF--ON--OFF--ON within a one minute
period will cause a “Limit Cycle Timeout” alarm. In such case sag correction will be inhibited for
one minute, after which the alarm will automatically reset.
WARNING: This system is interlocked: Opening HC-DySC doors while the
system is in operation will result in loss of power to protected loads, unless the
bypass switch is in the Bypass mode (see HC-DySC SYSTEM OPERATION)
