1.6.4 Switch Test Activate ‘Switch’ function in menu 1.
The switching pressure of a pressure switch can now be
monitored by connecting the contacts of the pressure switch
between the INPUT 'GND' and 'SWITCH' sockets on the
connection panel and pressurizing the pressure switch.
1.6.5 RS232
If the RS232 facility is to be used then connections to the 8-
way socket must be made to the specifications given in the
table below. Alternatively an RS232 communication cable
can be purchased from GE suitable for most RS232
applications as shown below.

CAUTION:
1.6.7 Voltage Output
Connect the PC6-IDOS to a printer or computer using a suitable
cable (not supplied) as detailed above and set the parameters as
detailed in Para. 2.5 & 2.7. The output can now be obtained as
‘single shot' or ‘timed' as follows:
- This output is available in Display mode when
RS232 status is ON & Log status is OFF. The output cycle is
initiated by pressing the
key. Pressing the key cancels
the output. Once initiated, the output is repeated at the selected
time interval (see ‘Event' function, page 26 ) until the
key is
pressed.
The internal battery pack may be
recharged (when indicated by the battery low message) by
plugging the charger (supplied) into the 'CHARGER' socket.
When recharging internal batteries, only the charging
unit supplied with the PC6-IDOS should be used.
A voltage of +10V or +24V may be
sourced from the PC6-IDOS by connecting to the 2 mm sockets.
A typical application for this voltage output would be to power a
pressure transmitter. ( see Fig. 3. page 10 )
To switch on voltage output function:-
a) Press the
key twice to activate 'Set' menu.
b) Select 'V-out' and press the key.
c) Select 'ON' and press the key.
1.6.5.2 Single Shot - This output is always available in Display
mode when RS232 status & Log status are OFF. The output is
obtained each time the
key is pressed (provided any
previous output is complete).
The PC6-IDOS must be switched off prior to
connecting or disconnecting the RS232 cable.
