- Page 14 If a particular alarm signal is programmed to cause the system to shut down (e.g. MIN conductivity limit) or if shutting down is specified (e.g. motor circuit-breaker), the alarm signal cannot be cancelled in the LCD until the fault has been rectified. There are some fault alarm signals which permit the system to be switched back on before the fault has been rectified.
- Page 17 "Pressure pump", "input valve" and "concentrate valve" outputs are standard features of the system. The timing of the activation of the outputs is defined during the programming of the individual phases in programming steps 9 to 17.
- Page 18 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.
- Page 19 The "FULL" and "EMPTY" inputs are standard features. Define whether the inputs are activated are activated when the contact is open or closed. This is defined in programming step 4.4. Optionally, the controller can be equipped with a motor circuit-breaker for 1-phase high-pressure pumps.
- Page 21 basic settings should only changed by a duly authorised expert. Take a note of the basic settings in the free fields in the following flow diagrams. Keep this manual safe for use by operat- ing and servicing personnel. The basic settings may be changed at any time.
- Page 22 The measuring probe is installed in the permeate flow. Choose a probe with an adapted cell constant, corresponding to the water conductivity being measured. A cell constant of 0.01 cm to 10.00 cm can be pro- grammed for the conductivity meter.

- Page 24 The system features FULL and EMPTY inputs for the purposes of reservoir control. The functions of inputs IN1, IN2 and, if there is a plug-in IF card installed, IN3 are programmable. You have a choice of 5 options. Each function may only be utilised once. ST = Stop EX = External switch EP = Exceeded pressure...
- Page 25 Parameters still have to be input for some input functions. The "full/empty level switch" and "power failure" programming steps are always displayed. The others are only displayed if the function has been selected beforehand.

- Page 28 If the controller has been equipped with the IF plug-in card, two additional output functions can be selected from a choice of 6 for the OUT1 and OUT2 outputs. Each function only exists once. If the same function is se- lected for both outputs, the output relays function in parallel.
- Page 29 Parameters still need to be entered for some output functions. The following programming steps are displayed, depending on the output functions selected in programming steps 6.1 and 6.2. These parameters are only displayed if there is an IF plug-in card installed.

- Page 32 The production phase comprises 3 time-dependent stages which run in consecutive order. The system remains in the subsequent stage 4 position until the production phase has ended. If production is over and the pressure pump is in operation, the system remains in this position for a further 3 seconds before the pump starts running.
- Page 33 If the input function ST=stop has been selected in any of programming steps 4.1 to 4.3 and this function is assigned to the production or rinse phases in programming step 5.13, in the following programming step, specify which phase the system switches to when the stop input is activated. If standby 1 has been selected, the system switches to standby if the stop input is activated (programming step 12.3).
- Page 34 The standby phase comprises two stages. The first time-dependent stage puts the system on standby. The system remains in stage 2 until the next production, rinse or maintenance phase. You define whether the input valve and the concentrate valve are open during these 2 stages.
- Page 35 The “rinse after production“ phase comprises 3 time-dependent stages which run in consecutive order. If the rinse phase is over or interrupted and the pressure pump is in operation, the system remains in its current position for a further 3 seconds before the pump starts running. You define whether the input valve and the concentrate valve are open during these 3 stages, and when the pressure pump kicks in.
- Page 36 The “rinse during standby“ phase comprises three time-dependent stages which run in consecutive order. If the rinse phase is over or interrupted and the pressure pump is in operation, the system remains in its current position for a further 3 seconds before the pump starts running. You define whether the input valve and the concentrate valve are open during these 3 stages, and when the pressure pump kicks in.
- Page 37 The “rinse during production“ phase comprises three time-dependent stages which run in consecutive order. If the rinse phase is over or interrupted and the pressure pump is in operation, the system remains in its current position for a further 3 seconds before the pump starts running. You define whether the input valve and the concentrate valve are open during these 3 stages, and when the pressure pump kicks in.
- Page 38 The maintenance phase is started from the stop during maintenance phase. It comprises two time-dependent stages which run in consecutive order. Once this phase is over, the controller returns to the stop during maintenance phase. You define whether the input valve and the concentrate valve are open during these 3 stages, and when the pressure pump kicks in.
- Page 39 In this programming step, specify the phase in which the system should be before and after the maintenance cycle (programming steps 16.1 to 16.4). This phase is also used when the "stop" input is activated during the maintenance cycle. In the case of equipment with an IF plug-in card, you also specify whether the output relay is activated for each of the output functions selected in programming steps 6.1 and 6.2.
