RG 210
once the heat-up process of one probe is completed, the yellow LED
of the corresponding probe goes out. If the PTC thermistor of a
probe is submerged in liquid or if the heat-up process of the probe is
not yet completed or the probe is not connected or short-circuited,
the yellow LED of the corresponding probe lights up.
Logical connection between the two probe signals and an output sig-
nal: If both probes are no longer submerged in the liquid, the green
LED "Release" lights up and the output relay is energised. If both
probes are submerged in the liquid, the green LED "Release" goes
out and the output relay is de-energised.
Operating mode "Emptying": level control for emptying
Both PTC thermistor probes "Probe 1" and "Probe 2" must be con-
nected. The following applies to both probes in this operating mode:
If the PTC thermistor is submerged in the liquid, the yellow LED of
the corresponding probe goes out. If the PTC thermistor of a probe is
exposed to air or if the probe is not connected or short-circuited, the
yellow LED of the corresponding probe lights up.
Logical connection between the two probe signals and an output sig-
nal: If both probes are submerged in the liquid, the green LED "Re-
lease" lights up and the output relay is energised. If both probes are
no longer submerged in the liquid, the green LED "Release" goes out
and the output relay is de-energised.
General information
In case of a power failure, the relay is always de-energised. When
power is available again, both probes must either be exposed to air
or submerged in the liquid before release is possible. A start delay of
approx. 15 seconds prevents a release before the heat-up phase is
completed.
RG 210 can be operated with or without additional external devices.
The following types of additional devices can be used: visual and
audible alarm units, telecommunication devices, building control sys-
tems, building automation systems, pumps, valves, etc.
