About this chapter
The Description of functions is divided in two levels:
•
Basic principles – Basic principles containing a
survey of the function. This text is written with an
italic typeface. The text refers to the diagram
”Basic principles” in chapter ”Diagrams”.
•Enhanced information – Enhanced information
about the function. Normal typeface is used in this
text. This text refers to the following diagrams in
chapter ”Diagrams”:
– Pneumatic block diagram
– Electronic interconnection.
Text written in SMALL CAPS refers to block names in
the diagrams mentioned above.
Battery drawer
The battery drawer contains functions for power
supply and communication.
1. AC/DC Converter
The AC/DC CONVERTER, containing the mains power
rectifier and the transformer, is a complete unit that
is mounted on the Power & Communication interface
casing. The AC/DC CONVERTER is electrically connected
to PC 1675 POWER SUPPLY.
There are two mains power inlet fuses in the AC/DC
CONVERTER. The fuses and the AC/DC CONVERTER FAN
are the only spare parts available for the AC/DC
CONVERTER.
The AC/DC CONVERTER FAN pulls cooling air into the
converter compartment. If the fan fails, the signal
FAN_FAIL generates a diagnostic log message.
If the AC/DC CONVERTER is overheated (above +90°C /
194°F), e. g. due to fan failure, the AC/DC CONVERTER
will be disabled. The KION / KION-i workstation will
then be power supplied by the INTERNAL BATTERY.
When the AC/DC CONVERTER cools down, it will
automatically be enabled.
Technical data for the AC/DC CONVERTER:
• AC/DC CONVERTER input: 100 – 240 V AC, 50 – 60 Hz.
• AC/DC CONVERTER output: Max. 400 W, output
voltage level 21–30 V DC controlled by an analog
signal from the Charging/Discharging control block
on PC 1675 POWER SUPPLY.
• Fuses: T 6.3 AL / 250 V AC (2 pcs).
2. Internal battery
The INTERNAL BATTERY (two serial connected 12 V
sealed lead acid batteries) supplies the KION / KION-i
workstation with backup power for min. 30 minutes
with full charged battery.
The INTERNAL BATTERY is used as an internal 24 V
backup. The batteries are rated 12 V, approx. 24 Ah.
The INTERNAL BATTERY is continously charged when the
KION / KION-i workstation is connected to mains
power. Charging time for empty batteries is approx.
6 hours.
The actual INTERNAL BATTERY capacity is continously
displayed on the KION Monitor. The battery capacity
indication, bargraph with %, is related to actual
battery voltage. ”100%” is indicated when trickle
charge level is reached (fully charged).
The following applies concerning battery voltage
supply:
• Battery voltage supply is used as soon as the
AC/DC CONVERTER voltage is less than the battery
voltage (e.g. if the power consumption is too high).
• If the AC/DC CONVERTER output voltage is below
19V (e.g. at loss of mains power), a ”Switching to
battery” alarm indicates that battery voltage supply
is in use.
• First battery alarm ”Limited battery capacity” is
activated when battery voltage reaches below 23 V
(22 V if an EXTRA INTERNAL BATTERY is connected).
These voltage levels correspond to ”20%”
indicated.
• Second battery alarm ”No battery capacity” is
activated 10 minutes after first battery alarm or
when battery voltage is below 22 V (21.5 V if an
EXTRA INTERNAL BATTERY is connected). These voltage
levels correspond to ”0 %” indicated.
• All functions will be cut off when battery voltage
reaches below 21 V.
Battery capacity indication and alarms are generated
via the ALA power supervision function.
Service interval for the INTERNAL BATTERY:
• The INTERNAL BATTERY must be checked during the
”Twelve months maintenance”.
• The INTERNAL BATTERY must be replaced every three
years. After replacement, allow the batteries to
recharge before clinical use of the KION / KION-i
workstation.
The lifetime of the INTERNAL BATTERY is reduced if it is
used frequently to supply the KION / KION-i
workstation with operating power or if the battery
temperature is above +50°C (122°F) e. g. due to
BATTERY DRAWER FAN failure. In such case, it is
recommended to check the INTERNAL BATTERY with
shorter intervals than 12 months.
