Additional output functions
The IF card is available as an optional extra, providing you with another 2 programmable floating out-
puts. The functions described below (dosing, Additional program, permeate valve or alarm relay) can
optionally be assigned to those outputs.
Each function only exists once. If one of the functions is programmed for both of the additional out-
puts, the two output relays operate in parallel.
You can specify in programming step 6.3 when the functions should be activated with the voltage
switched on or off.
Dosing
The relays floating contact can be used to
control dosing systems or, depending on the
wiring arrangement, to activate dosing pumps
or valves directly.
The phases in which activation takes place can
be defined in programming steps 9 to 17.
The dosing time can be limited to anything
between 1 and 65,000 seconds. However, it
may not be any longer than the selected
phase. Moreover, pulsed dosing is also an
option.
The appropriate values are entered in pro-
gramming steps 7.1 to 7.3.
Additional program
Any control functions can be defined using the
floating contact.
The phases in which activation takes place can
be defined in programming steps 9 to 17.
The dosing time can be limited to anything
between 1 and 999 minutes. However, it is
cancelled prematurely if it is longer than the
current phase and has not been selected for
the subsequent phase.
A pick-up delay of between 0 and 999 seconds
can also be defined.
The appropriate values are entered in pro-
gramming steps 7.4 and 7.5.
Warning! In the case of the MAINTENANCE
phase, simply specify whether the relay is
switched on or off.
Permeate valve
If it is appropriately wired, the relays floating
contact can be used to activate a permeate
valve. Depending on the installation of the
valve, it can be used to block the line to the
consumer or to flush the modules.
The permeate valve is only monitored, conduc-
tivity-dependent, during the "PRODUCTION"
phase.
The permeate flush valve remains closed while
the conductivity is below the defined limit. This
limit and a drop-out and pick-up delay are en-
tered in programming steps 7.6-7.8.
Define in programming steps 10 to 17 whether
the valve should be open or closed n the case
of the other phases. Conductivity-dependent
monitoring does not occur.
Alarm relay
The relays floating contact can be used to
activate control consoles or, depending on the
wiring arrangement, to connect signal devices.
The events which should prompt an alarm
signal can be programmed in programming
steps 7.9 to 7.11.
