5.6 Relay contact configuration
The function group RELAYS is only accessible for instruments equipped with the Plus packet.
The relay contacts described below can be selected and configured as required (max. four
contacts depending on options installed):
• Limit contactor for pH / redox value: R2 (1)
• Limit contactor for temperature value: R2 (2)
• P(ID) controller: R2 (3)
• Timer for cleaning function: R2 (4)
• ChemoClean function: R2 (5) (for Plus package)
• Neutralisation controller: R2 (6) (for Plus package)
5.6.1 Limit contactor for pH/redox measured value and temperature
The relay contacts in the Liquisys M can be
assigned different functions.
Switch-on and switch-off points and pickup
and dropout delays can be defined for the
limit contactor. Moreover, an alarm threshold
can be set to issue an error message and to
start a cleaning function.
These functions may be used for pH/redox
and temperature measurement.
Please refer to Fig. 5.10 for a graphic
representation of the contact states of any
relay or alarm contact.
When the measured value increases (max.
function), the relay contact is closed at time t
2
when the switch-on point has been exceeded
(t
1
) and the pickup delay (t
2
– t
1
) has expired.
When the alarm threshold (t
3
) is reached and
the alarm delay (t
4
– t
3
) also has expired, the
alarm contact is switched.
When the measured value decreases, the
alarm contact is reset when the measured
value drops below the alarm threshold (t
5
).
The relay contact is also reset (t
7
, after the
dropout delay t
7
-t
6
).
When the pickup and dropout delays are set
to 0 s, the switch-on and switch-off points are
identical to the contact switching points.
Settings analogous to the max function can
also be made for a min function.
