5.2 Electrical connections
NOTE
External connections and extension lines must be provided with a grounded conductor lead
(3-pole couplings, cord or plug equipment). All used power cords must meet the input power
requirements.
It is recommended that all components of the Flash system are connected to a common ground.
The detector should not be connected to an electrical line which also serves units with a large
power drain or which may be subject to power surges. Such units include refrigerators, ovens,
centrifuges and fume hoods.
NOTICE
Risk of device damage by wrong mains supply.
• External mains supply must meet the voltage given on the type plate
• Check for sufficient grounding
All electrical connections are made via the supply panel (Fig 5.7) on rear panel.
Connecting the Recorder/Integrator:
If a recorder or integrator is employed, connect the recorder input to the 1 V output terminal on
the rear panel of the detector (Fig 5.7) and to the appropriate socket on the recorder/integrator.
Connecting the External Autozero:
If the external autozero function is to be employed, plug the cable that is supplied into the Ext
Autozero socket on the detector (Fig 5.7) and to the appropriate socket on the controlling device
(e.g. autosampler, pump, etc.).
Refer to section 6.2.2 to operate external autozero signal.
Connecting the External Events Cable:
If the external events functions are to be employed, plug the cable that is supplied into the ap-
propriate socket on the back panel of the detector (Fig 5.7) and to the appropriate socket on the
controlling device (e.g. autosampler, pump, etc.).
The white cables are contact closure “output” cables that provide the ready/non-ready informa-
tion to an external device. The detector will be in the “not-ready” mode (the contact will be in
closed position) if any one of the following conditions is observed:
• The lamp is off.
• The temperature is not at the indicated setpoint.
• The temperature is at the indicated setpoint but is not stable.
• The pressure is below 2.0 bar.
NOTE
The electrical consumption of the controlled device must not exceed 20 mA under 12 VDC.
