3.2.4. Mains Power Supply ZG0199
The Mains Power Supply ZG 0199 (Fig. 3.4), available
to
order, .may either be used fitted
inside the
Supply Compartment
of
the Indoor Climate Analyzer,
or
externally. It may be
powered from
50
to
400Hz
single phase
AC
mains, and when adjusted as described in
its
Instruction Manual can accept voltages
of
100, 115, 127, 220
or
240
V.

Power
Supply
ZG
0199
for
external
use with the
Analyzer
Type 1213
The procedure
for
installing the ZG 0199 in the Supply Compartment
of
the Type 1213 is
the same as that described in section 3.2.2
for
the Battery Box ZG 0146. Care should be
taken
to
locate the Mains Power Supply the right way up. See Fig.3.2.
To
use the
ZG
0199 externally
for
powering the instrument,
and/or
recharging NiCd cells
if
they are fitted, connect one end
of
Control Cable
AQ
0035
to
the POWER/CHARGE
socket on the Rear
Panel
of
the Type 1213, and the other end
to
the OUTPUT socket on
the
ZG 0199. The
ZG
0199 provides sufficient current
to
simultaneously recharge cells
and
to
power the instrument.
A WARNING: If non-rechargeable cells are installed in the instrument, ensure that the OUT-
PUT
SELECTOR switch on the ZG 0199 is set
to
DRIVE
VOLTAGE
"On" - CHARGE
"Off"
before connecting the mains supply.
To
power the Type 1213 and simultaneously charge rechargeable cells installed in the
instrument, set
OUTPUT SELECTOR on the ZG 0199
to
DRIVE
VOLTAGE
"On"
-
CHARGE
"On". The charge time
for
completely exhausted cells is approximately 14
hours.
If the ZG 0199 is connected externally
to
the Type 1213 and switched on, power will
automatically
be taken from
it
in preference
to
any installed batteries unless the power
source
voltage is lower than the battery voltage, in which case current will be drawn
from the batteries.
If in doubt, remove the batteries.
Note: If batteries are installed, switching
off
the ZG 0199 will cause the Type 1213 to
continue
to
run from its batteries, unless the Power Switch
of
the Analyzer is set to
"Off".
3.2.5. External DC
20
An external
DC
source, such as a car battery, may be used
to
power the Indoor Climate
Analyzer
via the POWER/CHARGE INPUT socket on the rear panel. This has the pin
connections shown in Fig. 2.8 and accepts the 7-pin
DIN
plug JP 0710 supplied. The
