GIE 4820/3A/3.45KW Power Supply System User Manual
3.3.9 Alarm Testing on Gate Magnetic, Smoke and Waterlogging
If sensors for gate magnetic, smoke and waterlogging have been installed, change
the status of sensors. The background equipment should give the corresponding
alarms.
Note:
1) If the terminal of corresponding load and battery circuit does not connect with
load or battery during testing stage, on its midair state, the alarm of circuit breaker
disconnection for corresponding load or battery cannot be reported accurately.
2) Be sure that system configurations are restored to normal status after testing.
3.3.10 Viewing Operating Information
After the power is on, simple operating information can be viewed via indicators on
the monitoring panel. For detailed information must be looked over through the
background monitoring.
3.3.11 Canceling Battery Protection
If the user thinks it is more important to keep power supply to loads than to protect
the battery, and battery protection in case of AC outage is not desired, load and
battery shutdown permission state or battery shutdown permission state can be set
to no-permission state via the host.
Note:
When battery is discharged to protection value, the time for continued power supply
is very short. It is impossible to obtain the long time operation of loads with battery
sacrificed.
3.4 Routine Maintenance of the System
3.4.1 Inspection and Repair of Fan and Dust Mesh of the Rectifier Module
Dust will accumulate on the baffle plate after the rectifier works in dusty and windy
environment for a long period. To ensure long-term reliable and smooth operation
of the rectifier, it is necessary to clean the fan and baffle plate regularly.
Fan is wastage device, and it must be cleaned and replaced after it works for a
certain period. Fan replacing method: first unscrew the screws on the top right
corner of the fan to remove it, and then disconnect power cable. Do not touch the
devices within the rectifier module with hand during the cleaning or replacement.
