also be used as a stand-alone protection module.

The IO 112 interface has

• three inputs for measured values

• one potentiometer for setting of limits

• indicator lights indicating the

- measured value of the input

- value of the limit set

- alarm source

- pump status.

Before installing the IO 112, make sure

that the electricity supply has been

switched off and that it cannot be acciden-

tally switched on.

IO 112 must not be installed in potentially

explosive environments. Ex-approved

pumps may, however, be installed in an

explosive environment.

6.2 Mounting

IO 112 is prepared for mounting on a 35 mm DIN rail

(EN 50 022).

Fit the IO 112 module by hooking the top on the DIN

rail and clicking the bottom onto the rail.

Fig. 3 Mounting on DIN rail

The IO 112 module can be removed by pushing it

upwards and free of the DIN rail.

6.3 Electrical connection

All terminals are rated for maximum 8 A. The termi-

nals 8, 9, 10 and 12 are for wire size AWG 28~12;

terminal 13 is for AWG 28~16.

Voltage rating of the individual terminals, see

14. Electrical data.

Note: If the PT function is not used, terminals P1

and P2 must be connected by a jumper. See fig. 4.

Fig. 4 Jumper between P1 and P2

6.3.1 EMC-correct installation

It is especially important to ensure an EMC-correct

installation of pumps with frequency converter.

The following rules must be observed:

• Connect the cable screen to earth.

• Do not twist screen ends, as this will destroy the

screen effect at high frequencies. Use cable

clamps as shown in fig. 5.

• It is important to ensure a good electric contact

from the mounting plate through the mounting

screws to the metal cabinet of the frequency con-

verter.

• Use toothed washers and a galvanically conduct-

ing mounting plate.

Fig. 5 Screen fixed with cable clamp

TM03 5582 3806

The installation must incorporate a circuit

breaker in order to switch off the phase

voltage on the terminals of pos. 10. See

fig. 1. It must be close to the IO 112

module and easily accessible for the

operator. It must be marked as circuit

breaker for IO 112.

The circuit breaker must be according to

IEC 60947-1 and IEC 60947-3.

TM03 2801 4805

The insulation between the cabinet in

which the module is fitted and the input

terminals for sensors must have a dialec-

tic strength of 2210 VAC, or the cabinet

must be connected to earth.

The terminals T1 and T2 (pos. 8) may be

connected to phase voltage. See fig. 1.

7. Settings

7.1 DIP switches

7.1.1 Selection of operational input

DIP switches 1 and 2 are used for choosing between

bus configuration, analog input, temperature sensor

input and counter input.

Bus configuration

If switches 1 and 2 are set to bus configuration,

IO 112 is operated from for instance Modular Con-

trols via GENIbus.

Analog input

If switches 1 and 2 are set to analog input (AI),

IO 112 is operated by means of the reset button and

rotary potentiometer of the module. See fig. 1.

The analog input is used for instance for the connec-

tion of a level sensor.

Temperature sensor input

If switches 1 and 2 are set to temperature sensor

9. Start-up

When the IO 112 has been installed as described in

6. Installation, start-up must be carried out by an

authorized person.

1. Switch on the electricity supply to the IO 112

before starting the pump.

2. IO 112 now carries out a self-test. All indicator

lights on the front panel will be on for a few sec-

onds. If IO 112 does not detect any fault, all indi-

cator lights will go out. If a fault is detected, the

indicator lights for the actual fault will illuminate.

3. Check that there are no warnings or alarms

before switching on the pump.

10. Indication

On the front of IO 112, a column of six indicator

lights show the measured value. Depending on

whether the measured value is set to count up or

down, the indicator lights will illuminate from the bot-

tom or the top.

Fig. 11 Indicator lights and reset button on

IO 112

10.1 Alarm resetting

Alarms can be reset by means of terminals R1 and

R2 (pos. 9).

Manual resetting

Alarms can be reset by short-circuiting R1 and R2.

The reset button (pos. 1) also short-circuits R1 and

R2.

Automatic resetting

If a permanent short-circuit is made between R1 and

R2, alarms are automatically reset when the alarm

cause has disappeared.

11. Maintenance

IO 112 requires no maintenance. IO 112 must only

be cleaned with a dust-free cloth.

12. Service

IO 112 cannot be serviced. If the module is faulty, it

must be replaced.
