5.2.1 Handling Controller Alarms
You can query the controller alarms through LCD screen of the controller.
Alarm type
The controller alarms are classified into three types: critical alarm, observation alarm and no alarm.
Critical alarm: These two types of alarms have strong impacts on the system performance. Whenever these alarms
are generated, you should handle them immediately. The alarm indicators (see Figure 5-1) will be on and audible
indication will be given.
Observation alarm: When this type of alarm is raised, the system maintains normal output for a while. If the alarm
occurs during watch time, it should be handled immediately. If the alarm occurs during non-watch-time, handle it
during watch time. The alarm indicators (see Figure 5-1) will be on when the observation alarm occurs.
No alarm: Alarms set as ‘no alarm’ by the users, will generate no visible or audible indication and the system works
normally.

If the failure does not last long, the battery will power the load. If the cause is unknown or the
failure lasts too long, a diesel generator is needed. Before using the generator power to supply
the power system, it is suggested to run the generator five minutes to minimize the impact on the
power system
Pull out the rectifier to check if the fan is obstructed. If yes, clean it and push the rectifier back. If
the fan is not obstructed or if the fault persists after cleaning, replace the fan
Check if the communication cable is connected properly between rectifier and controller. If yes,
restart the rectifier. If the alarm persists, replace the rectifier
Check the temperature around the temperature sensor is too high, if so, find the cause and
reduce the temperature
Check if the corresponding MCB is switched off. If the MCB is open, find out the fault and remove
it. Otherwise, the alarm circuit is faulty. Please contact Emerson
Find out the rectifier that caused the over-voltage alarm. pull out all the rectifiers under the
circumstance that the battery can supply power normally. Then insert the rectifiers one by one.
When inserting a certain rectifier, the system triggers over-voltage again, that rectifier is
over-voltage, replace it
1. Check if any rectifier is inoperative, or has no output current. If yes, replace it.
2. Check if the total load current exceeds the total rectifier current during float charge. If yes,
disconnect some loads or add more rectifiers to make the total rectifier current bigger than 120%
of the total load current with one redundant rectifier
Check if there is mains failure, and the battery voltage is lower than the value of ‘LVD2’.
The rectifier with the fault indicator (red) on is faulty.
Power off the rectifier, and then power it on after a while. If the alarm persists, replace the rectifier
Check if the AC over-voltage value is too low. If yes, change the value.
A mild over-voltage does not affect the system operation. However, the rectifier will stop
operation when the mains voltage is more than 305V. If the mains voltage is above the AC
over-voltage value, the mains grid should be improved
Check if the AC under- voltage value is too high. If yes, change the value.

damage.
3. Hold the rectifier handle and push the new rectifier into the slot just vacated and make sure the connection is good.
After a brief delay, the run indicator of the rectifier will turn on and the fan will start running.
4. Check whether the new rectifier works normally.
You should make sure that:
1) The monitoring unit recognizes the new rectifier.
2) The new rectifier shares current with other rectifiers.
3) When this new rectifier is pulled out, there is a corresponding alarm and the monitoring unit displays the alarm.
If the new rectifier passes all the above tests, the replacement is a success.
5. Push the handle back into the front panel to fix the rectifier, and tighten the fixing screw of the rectifier handle.
5.3.2 Replacing Controller
Controller fault: the run indicator (green) is off and the LCD screen does not display (external alarms may also be
triggered if a background system is connected).
Please check whether the system bus voltage is normal, and the controller connection terminal is reliable. If the above
two points are normal, then the controller is faulty, replace a new controller.
The replacing procedures are as follows:
1. Safety preparation
Attach one end of the effective grounding strap to the wrist and the other end to a suitable ground.
2. Loosen the locking screw on the controller to pull out the controller from the subrack power system until the
terminals J6, J7, J2 (when the temperature sensor is configured) are exposed. Unplug the connection terminal on J6,

Description
The rectifier provides over-voltage hardware and software protection.
The hardware protection point is 59.5V ± 0.5V, and it requires manual
resetting to restore operation. The software protection point is between
56V and 59V (0.5V above output voltage, 59V by default), and can be
set through the controller
There are two software protection modes, which can be selected
through the software at the host:
1. Lock out at the first over-voltage
Once the output voltage reaches protection point, the rectifier will shut
off and hold that state. it requires manual resetting to restore the
operation
2. Lock out at the second over-voltage
When the output voltage reaches the software protection point, the
rectifier will shutdown, and restart automatically after 5 seconds. If the
over-voltage happens again within a set time (default: 5min.
Configurable through controller), the rectifier will shut off and hold that
state. It requires manual resetting to restore the operation
Manual resetting: Resetting can be done manually through the
controller, or by removing the rectifier from system
Output voltage can rise slowly upon rectifier start up. The rise time is
configurable
Rectifier fan speed can be set to half or full speed
