GENERAL: A power supply system can be described as a system, which by means of batteries is able to supply the consumer with DC current in a certain period of time, if the mains voltage fail to appear. The system is build up by an automatic battery charger and a number of batteries. Beyond this the system can be provided with different control instruments, alarms, extra output connections etc. The system is in principle maintenancefree, but ought to be examined, cleaned and tested at least once a year. |

| Ammeter
DC Voltmeter DC Mains voltage : Red control diode Main charge : Yellow control diode Equalizing- and trickle charge: Green control diode Switch: MAN-OFF-AUTO |
| BEFORE USE / STORAGE: | Back to menu: |
| The system is delivered ready for use with charged batteries, but the plug connection between the batteries is disassembled. The system can remain in this condition for one month from the day of delivery. By longer time of storage, the batteries must be trickle charged as follows: |
| a) Switch "MAN-OFF-AUTO" is placed in position "OFF". |
| b) Mains voltage is connected. |
| c) The plug connection to the batteries is assembled (is placed behind the front cover). (Voltmeter deflection). |
| d) Switch is placed in "AUTO" (red control diode illuminates). |
| After
about 4 seconds the yellow control diode will switch on and the main charge
has started. The charging must at least continue until the green control diode (equalizing and trickle charge) switches on. In this phase the yellow control diode switches off and the batteries are now charged. |
| e) Put the switch in position "OFF". |
| f) Disassemble the plug connection to the batteries. |
| The
system can now remain in this condition for one more month, after which
the procedure must be repeated. NB! To avoid unintentional discharge of the batteries the switch should always be put in position "OFF" and the plug to the batteries disassembled. Ambient temperature for the system: -30°C to + 45°C. Humidity: Until 90% relative non condensation. |
| PREPARATION FOR USE: | Back to menu: |
| a) Check the switch for correct start position "OFF". |
| b)
The plug connection to the batteries is assembled. (Voltmeter deflection). |
| c) Place the switch in position "AUTO" (red control diode illuminates). |
| d) Before use, the batteries should be charged until the green control diode switches on. |
The system is now ready for use and takes no further inspection or maintenance expect from periodic control. Although the system should be examined, cleaned and tested at least once a year. |
| SYSTEM FAILURE: |
| If a system failure should appear in the automatic control of the battery charger it is possible to declutch it by means of the switch manual position "MAN". With the switch in "MAN" it is VERY important to make sure that the batteries are not to be over charged. The voltmeter reading could be kept between 2 Volts and 2,35 Volts per cell. If the reading is higher than 2,35 Volts per cell, place the switch in position "OFF". If it is impossible to increase the batteries cell voltage to 2,35 Volts per cell with the ammeter showing charging current, it may be a defect battery or a bad connection. When the switch is in position "MAN" the control diodes are of no consequence. |

UNINTERRUPTIBLE POWER SUPPLY |
Back to menu: |
| GENERAL: |
| A
UPS power supply system (Uninterruptible Power Supply) can be described
as a system, which by means of batteries is able to supply the consumer
with AC voltage in a certain period of time, if the mains voltage fail to
appear. The system is build up by a battery charger part, an inverter part and a number of batteries. Beyond this the system can be provided with static switch, different control instruments, alarms, taps of battery voltage etc. The system is in principle maintenancefree, but ought to be examined, cleaned and tested at least once a year. |
| FOUNDATION PARTS: | Back to menu: |
| Automatic battery charger: | Type HE |
| Inverter: | Type WS, 230 Volts AC, 50 Hz sinus |
| Batteries: | Maintenancefree lead/acid |
| Cabinet : | Type
C, degree of protection IP 23 Type C, degree of protection IP 54 |
| INSTRUMENTS: | Back to menu: |
| Charge part: | Ammeter DC Voltmeter DC Mains voltage: Green control lamp Main charge: Yellow control diode Equalizing- and trickle charge: Green control diode Alarm for high/low battery voltage: 2 red control diode Switch: 1-0-2 (Manual bypass - off - on) |
| Inverter output : | Ammeter AC Voltmeter AC Output: Green control lamp Switch: 0-1 (off - inverter on) |
| BEFORE USE/STORAGE: | Back to menu: |
| The
system is delivered ready for use with charged batteries, but the plug connection
between the batteries is disassembled. The system can remain in this condition
for one month from the day of delivery. By longer time of storage, the batteries must be trickle charged as follows: |
| a) Switch "0-1" is placed in position "0". |
| b) Switch "1-0-2" is placed in position "0". |
| c) The plug connection to the batteries is assembled (is placed behind the frontcover). (DC- voltmeter deflection). |
| d) Mains voltage is connected. |
| e)
Switch "1-0-2" is placed in position "2". The green squared control lamp
by the switch illuminates. At the same time - after maximum 4 seconds - the yellow control diode "maincharge" will illuminate. |
| Maincharge has now started and must continue at least until the green control diode (equalizing- and trickle charge) switches on. In this phase the yellow control diode switches off and the batte- ries are now charged. |
| f) Place the 2 switches in position "0". |
| g)
Disassemble the plug connection to the batteries. |
| The
system can now remain in this condition for one more month, after which
the procedure must be repeated. NB! When the switch "0-1" is in position "1", the inverter is activated (NB: Consumption without load!). The batteries will be unintentionally discharge, if storage appears without the switch in position "0". |
| PREPARATION FOR USE: | Back to menu: |
| a) Check the switches for correct start position (left position "0", right position "0"). All lamps are extinguished and the instruments are in position "0". |
| b) The plug connection to the batteries is assembled. (DC-voltmeter deflection). |
| c) Place the left switch in position "2". The green control lamp and the yellow control diode illuminates. The instruments in the left side shows deflection. The charge part is active. |
| d) Charge the batteries to full capacity, before the inverter is turned on. |
| e) Place the right switch in position "1", green control lamp illuminates and the instruments in the right side show deflection. The inverter part is active. |
| f) Provided that the load is connected, the system is now running and takes no further inspec- tion or maintenance, except from visual periodic control. Although the system should be examined, cleaned and tested at least once a year. |
NB! From point e), the terminal strip "230 Volts" is actively supplied with AC output. EMERGENCY OPERATION 230 VOLTS AC 50 Hz As an emergency measure by a possible system failure the switch "1-0-2" is placed in position "1" (manual bypass). This causes that the supply mains voltage passes unimpeded till 230 Volts output. In this position charge part, batteries, inverter and instruments are out of operation (switch "0-1" must be in position "0". |
