Pointek CLS100 – QUICK START MANUAL
7ML19985QJ83
English
Definitions
The alarm conditions below can be detected in a fail-safe or non fail-safe mode.
Fail Safe
•
The sensor connection arrangement is fail-safe if the output status is in high
alarm status when power fails; open contact state prevents material overflow.
•
The sensor connection arrangement switches to the fail-safe low alarm status
when power fails; this open contact state prevents material running dry.
High Alarm
•
When material reaches a maximum process level, covering the probe.
Low Alarm
•
When material reaches a minimum process level, uncovering the probe.
Power/Alarm Wiring
Non Intrinsically Safe Version
LOW Alarm
WARNING: The DC input terminal shall be supplied from a source
providing electrical isolation between the input and output, in
order to meet the applicable safety requirements of IEC 61010-1.
Note
:
•
For terminal block equivalents, see
Enclosure Version
on page 7.
•
The solid-state output should only be used in circuits where the current is limited by a
proper load.
•
Due to the limited switching capabilities of the solid-state switch component, an
auxiliary relay must be applied when switching high-current/high-voltage apparatus.
WARNING - Parts of the enclosure are non-conducting and may
generate an ignition-capable level of electrostatic charge under
certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be subjected
to external conditions which might cause a build up of
electrostatic charge on non-conducting surfaces. Additionally,
cleaning of the equipment should be done only with a damp cloth.
Solid state switch output
12-33 V DC (polarity determines operation)
Note: numbers refer to enclosure versions. See p. 7
