The DSE9400 MKII Series battery charger can be used as a battery charger, DC power supply, or both at the same time. For instance, the unit can be used to power the generator control panels and charge the panel batteries or starter batteries at the same time.

With no AC input to the charger, the Fault relay is in it’s inactive state. This volts-free change over relay can be used to provide indication of alarms as detailed in the Protection section below.

When a suitable AC supply is connected, operation of the unit will depend upon the load connected to the unit’s output terminals :

6.2.1 PROTECTION

Alarms fall into two categories :

• Factory Configured, non-ajustable alarms.

• User Configurable Alarms, adjustable by DSE Configuration Suite PC Software.

6.2.1.1 FACTORY CONFIGURED ALARMS

Under the following conditions, the Fault Relay de-energises and charging is stopped (DC output is disabled) :

• Mains voltage > 310V (rms)

• Mains voltage < 85V (rms)

• Battery temperature > 60 ºC (if temperature compensation is enabled)

• Battery Charger ambient temperature> 85 ºC

• DC output voltage > 110% of Boost Voltage

• Short circuit / reverse polarity of the DC output.

6.2.1.2 USER CONFIGURABLE ALARMS

NOTE: For details of Battery Charger Configuration, you are referred to DSE Publication:

057-159 DSE9400 Series Battery Charger Configuration Suite Manual.

The following alarms are user configurable using DSE Configuration Suite PC Software. In each case, the Fault relay de-energises.

• DC Overcurrent alarm

• DC Overvoltage alarm

• Battery Temperature alarm. Activation of this alarm places the charger into Float mode.

• Mains Over Voltage alarm. Activation of this alarm places the charger into Float mode.

• Mains Under Voltage alarm. Activation of this alarm places the charger into Float mode.
