15. ALARMS AND TROUBLESHOOTING

15.1 Alarm summary table

When an alarm is activated a message identifying the alarm is displayed on the control module.

In the case of potentially dangerous alarms, the control module automatically shuts the humidifi er down.

For some alarm events (see Table 15.a), the signalling of the alarm is accompanied by the activation of an alarm relay, as described in: Other auxiliary contacts.

If the cause of the alarm is no longer valid, the humidifi er and alarm relay output can be reset automatically or manually, according to the type of problem, while the message displayed is deactivated manually by pressing the reset-PRG button.

If no longer active, the alarm status continues to be indicated until the reset-PRG button is pressed.

Still active alarms can not be reset.

In the type C control module the presence of an alarm is indicated by the lighting up of LED 9 and a combination of the LEDs 5 (Fig. 15.a); in the event of more than one alarm, these are indicated in sequence, at 2 second intervals.

In the type H or T control module, if not in programming phase, in the presence of an alarm LED 9 (see fi g. 15.b) begins fl ashing, while the display 5 indicates the alphanumeric alarm code.

The message is displayed cyclically, for a duration of two seconds, alternating with the measurement normally displayed (if the measurement normally displayed corresponds to a disconnected probe, the measurement is not displayed; this will automatically return to the display if the probe is reconnected).

In the event of more than one alarm, the display indicates all the corresponding codes in sequence, at two second intervals.

The alarm Ec cannot be reset.

In the event of the alarm CL (regular maintenance required), the alarm can be reset only by resetting the hour counter; see Resetting the hour counter.

The alarm E1 may appear in two distinct cases:

1. Malfunction when reading from the parameter memory (typically on start-up)

The default parameters are temporarily recalled, without being saved in the parameter memory (the parameters can be accessed and the correct values restored).

In any case the default parameter recall procedure is recommended; see Recalling the default parameters.

2. Malfunction when writing to the parameter memory (typically on pressing the PRG button)

Any modifi cations made will be cancelled; the parameters can be accessed, the values modifi ed and save operation repeated.

Table 15.a lists the alarm indications, the causes, the conditions and the possible solutions.

The remote terminal column indicates the alarm message that appears on the LCD display of the CAREL

Humivisor remote control panel, if one is connected to the humidifi er.

Check that the O-ring is not damaged or cracked; replace it if necessary.

• Drain electrovalve / drain pump (Fig. 17.d, part. no. 5 – Fig. 17.e, part. no.5)

Disconnect the power cables, remove the bobbin and remove the valve block after having unscrewed the two fastening screws from the manifold; remove any impurities and rinse; as regards the pump it is suffi cient to screw the clamping screw and remove possible impurities;

• Fill tank (Fig. 17.d, part. no. 1)

Check that there are no blockages or solid particles and that the conductivity measuring electrodes are clean, remove any impurities and rinse.

• Supply, fi ll, overfi ll pipe (Fig. 17.a, part. no.2-8 – Fig. 17.e, part. no. 3-1)

Check that they are free and do not contain any impurities; remove any impurities and rinse.

• Level control (Fig. 17.d, part. no.4 – Fig. 17.e, part. no. 4)

The level control must be released from the partition wall of the cabinet. Disconnect the connector from the terminals of the electronic board, take off the connection pipes. Release the spacers and the board, then take off the caps. Check that the o-rings are not damaged or cracked; replace them if necessary.

Check the cleanliness and free sliding of the two fl oat switches.

Clean all the components and reassemble and replace the device.

Carefully check that the connection pipes are properly fi tted and that they are not blocked or choked at any point.

IMPORTANT WARNING: after having replaced or checked the plumbing components, check that the connections have been carried out correctly, with their corresponding seals. Re-start the machine and run through a number of fi ll and drain cycles (from 2 to 4), at the end of which, applying the safety procedure, check for any water leaks.

17.2 Replacing the components

17.2.1 Non-stick fi lm

If requested as an option, the internal wall of the cylinder is lined with a non-stick fi lm to avoid lime being deposited on the internal walls of the cylinder. To clean or replace the fi lm, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• slowly remove the fi lm towards the mouth of the cylinder, without forcing it to avoid damage;

• open the fi lm after having released the click-on couplings;

• clean the fi lm with water and a plastic spatula if necessary; replace the fi lm if damaged;

• wind the fi lm around itself, reinserting the click-on couplings, and place it into the cylinder after the latter has been carefully cleaned and freed from deposits.

To replace the elements remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and loosen the fastening nuts from the threaded spigots of the elements.

Before reassembling the elements, check the state of the gaskets and replace them if necessary.

17.2.3 PTC overtemperature sensor

The PTC sensors (one for each heating element) do not require regular maintenance; they should only be replaced if the safety thermostat is activated due to operation without water: in fact, the intervention of just one PTC will cause the control module to shut-down operation.

To replace the sensors, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• disconnect the PTC sensor terminals (see Fig.: 7.p.a to 7.p.n);

• remove the electrical elements corresponding to the sensors being replaced;

• unscrew the PTC sensor (fi g. 17.a, part. no. 7 or Fig. 17.b part. no. 7 or Fig. 17.c part. no. 2) using a spanner on the hexagonal spigot, accessible from the under side of the cover;

• reassemble a new PTC sensor, replacing the o-ring and screwing it tight; reconnect the terminals;

• reposition the electric heating elements, making sure the PTC sensor enters into the corresponding sheath in the aluminium casting.

17.2.4 NTC temperature sensor (version with type H or T control module only)

As for the PTC sensors, the NTC sensor controlling the water temperature does not require regular maintenance.

To replace this sensor, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• disconnect the terminals of the NTC sensor (see Fig.: 7.p.a to 7.p.n);

• remove the sensor from the well housed in the measuring sheath (fi g. 17.a part. no. 2, or Fig. 17.b part. no. 1, or Fig. 17.d part. no. 11);

• reposition and connect the new sensor in the place of the old one.

17.2.5 Fuses (uxiliary circuit)

These measure 10.3 x 38mm and are housed in the fuse cartridge; to check the state of the fuses, check their continuity using a tester.

Use the types of fuses indicated in table 17.e.

17.2.7 Solid state relays (version with type H or T control module only)

The solid-state relays (one in the single-phase unit, two in the three-phase unit) can malfunction in one of two ways: by short-circuit or burn-out. The respective consequences for the supply of power are: continuous conduction or permanent opening.

In the event of malfunctioning, check the conduction of the relay using a tester.

For the replacement of the solid-state relay:

• turn the humidifi er off;

• open the disconnection switch in the power line (safety procedure);

• disconnect the power and auxiliary cables from the solid-state relay terminal block;

• remove the relay from the electrical panel by using a screwdriver to lower the fastening lever to the omega guide;

• replace the new relay on the omega guide and reconnect the wires as before.

17.2.8 Cooling fan and circuit breaker (version with type H or T control module only)

The SSR relays are cooled by a fan placed in the upper part, on the right side of the machine for the

20-60kg/h (44-132.2lbr/h) models, or placed on the base of the humidifi er for the models up to 10kg/h

(22lbr/h).

With insuffi cient ventilation the temperature of the electrical panel may rise excessively until, reaching

65°C, power to the solid-state relays is cut by a special Klixon (heat sensor, used in this application as circuit breaker - hereafter: circuit breaker), with manual reset (indicated by S2 in the wiring diagram) and without an activation signal. In this case, check:

• Whether the thermoprotective placed in the din rail near to the SSR relays has been working, or placed in front of the baffl e pressing the reset button (see Fig. 17.f);

• that the fan power board, fi tted in front of the baffl e, is powered (input terminals: 24 Vac) and in turn powers the fan (output terminals: 24 Vdc), (only for models up to).

If the fan is faulty:

- in the models up to 10 Kg/h (22 lbs/h):

• remove the baffl e, after having unscrewed the two side nuts for fastening to the partition of the appliance;

In case of malfunction, the thermoprotective can be replaced unscrewing the fastening screws;

- in the 20-27-40-60 Kg/h

( 44.1-59.5-88.1-132.3 lbs/h )

models:

• unscrew the 4 fastening screws placed on the right side of the structural work and extract the fan from the inside of the panel.

In case of malfunction, the thermoprotective can be replaced removing the polycarbonate transparent protection of the solid state relays and unscrewing the fastening screws.
