Check The Fuses Of The Mains Or Battery Power Supply - Eaton CEAG DualGuard-S Mounting And Operating Instructions

14 Check the fuses of the mains or battery power supply.

Check / replace fuses
The fuses for the mains power supply and the battery
power supply are located in the corresponding switch-
disconnectors or at the battery bank.
Furthermore, the end circuits in the SKU.1 modules and
individual circuits in other modules are fused.
WARNING!
Only open the switch-disconnectors if the system has
been disconnected beforehand.
ATTENTION!
Never remove the fuses of the installed modules ander
load.
14 Check the fuses of the mains or battery po-
wer supply.
To do this, the system must be blocked via the touch dis-
play.
Open the switch disconnector for the mains or battery
power supply.
Check the switch cabinet and existing subsystems to ensu-
re that all fuses in the load disconnector for the mains or
battery power supply meet the specified technical specifi-
cations and are properly inserted and intact.
Setting the charge retention voltage Battery
Control Module (BCM.1)
SAFETY INSTRUCTIONS
Safety instructions are marked with this symbol in the
text of the operating instructions. These should always
be read before starting work! Adjustment work on the
system may only be carried out by qualified electrici-
ans.
General information
If central battery systems are supplied without Batterys or
if the battery Typee is unknown, the charge maintenance
voltage is set at the factory to a value of 245 V (i.e. 2.27
V/Z). Depending on the battery Typee, the charge retention
voltage must be adjusted on site.
The charge retention voltage is set
as follows:
1. Press and hold the service pin of
the BCM.1 for a few seconds until
the green LEDs flash alternately.
The display on the touch display
is now controlled by the BCM.1.
Before this, it must be ensured
that there is no charging fault,
otherwise the error display on the
touch display will be activated.

2. The voltage „U=" , which is now shown in the display,
is the charge retention voltage to be set. The displayed
current „I=+"stands for the number of CMs foand on the
CCB bus, 1A = 1CM.
3. Now set the charge retention voltage using the „ISO
Test+" and „ISO Test" buttons (4) according to the bat-
tery manufacturer's specifications.
ATTENTION!
The charge retention voltage is always set to the approp-
riate value at a temperature of 20° C. The battery is then
charged at the correct voltage.
4. Press and hold the service button (1) again until the
green LEDs stop flashing to save the voltage.
The setting mode is automatically terminated after one
minute if no iso test button is pressed.
Testing the fuses of SKU.1 modules
For safety reasons, all SKU.1 modules should first be dis-
connected from the power supply.
Proceed as described for testing and replacement.
Checking and changing internal modules
The emergency lighting system must be enabled before
internal modules are checked or changed. The following
applies here: Before you disconnect the emergency lighting
system from the distributor of the general mains power
supply or battery power supply, block the system. Then
first disconnect the battery power supply and then discon-
nect the mains power supply. Secure the shutdowns as
long as you are working on the system or the system is not
in a safe operating condition.
NOTE!
If several systems are supplied by one battery bank, all
systems must be blocked before! Begin by activating the
lower level of the substations before activating the central
battery system.
Before reconnecting the power supply to the battery bank
connections for the battery power supply, turn on the
mains power supply and make sure that the system is blo-
cked. Only then do you switch on the battery power supply
at the battery bank.
ATTENTION!
Only fuses approved by CEAG
Notlichtsysteme GmbH may be
used.
