Drain temperature limitation

The system has a function to reduce the temperature of drainage water. During the cleaning cycle, if the system detects that the medium temperature

is higher than the set temperature, the system operates relay G.OUT, which remains energized until the drainage cycle ends. Energization of relay G.

OUT must be employed by the user as a method of reducing the drain water temperature of the device, for example through a valve that injects cold

water into the drain. Check the local regulations in force.

Faults

Abnormal operating conditions do not cause the device to stop operating but are shown on the display, making it possible to prevent possible more

serious problems (red LED flashing on the front panel). Faults are also recorded in a specific memory zone accessible via Modbus. The fault signal

persists until the user performs an alarms/faults reset, operating on the user interface or via Modbus, or when the fault in question is resolved. Contact

Caleffi technical service if you are unable to solve the problem unassisted.

Temperature 1 above maximum value set for drain

Temperature below minimum value, risk of frost

Pressure above maximum absolute level

Temperature above maximum absolute level

Discharge air vent blocking condition

Filling not completed error

Incorrect offset detected

Error: no power supply

Alarm management

The alarms (or blocking alarms) show conditions that prevent correct operation of the device or conditions of danger for the system. Following

identification of a possible hazard condition, the system assumes standby status and remains in a condition of safety to limit any possible damage or

malfunctions of the main system. Signalling of the alarm state is provided by the user interface (red LED steady on), and via the alarms signalling relay

(ALARM relay, closing), and via Modbus, by means of specific registers that indicate the type of alarm identified. The alarms are recorded in a suitable

memory zone and can be read and checked via ModBus. In the case of non-resettable alarms, following the corrective action an "alarms reset" is

required to allow the device to perform a loading cycle and assume correct operating status: during this phase, check that there are no anomalous

operating conditions.

NOTE: On the main page the error is indicated, e.g. as E01, while in the alarms history only the identification number 01 is shown.

Problem

Corrective action

bring the circuit up to pressure,

vent the circuit and perform an alarms reset operation

depressurize the system and, in conditions of safety, check the

correct insertion of pressure sensor P1, if necessary removing

it momentarily and then refitting it in its seat. Clear the alarm

with an alarms reset operation.

check that any shut-off valves installed upstream from the

device are open, check the direction of flow and perform an

alarms reset

pressurize the system

and perform an alarms reset.

depressurize the system and, in conditions of safety, check the

correct insertion of pressure sensor P1, if necessary removing

it momentarily and then refitting it in its seat. Clear the alarm

with an alarms reset operation.

check and restore the seal of the additives filling cap. Perform

an alarms reset

Temporarily close the air vent valve cap and isolate and empty

the device and then replace the dirty air vent valve. Perform an

alarms reset.

disconnect the electric supply, isolate and empty the device

and replace the drain ball valve. Reconnect the electric supply

and perform a device reset.

check all the seals and tighten wherever possible

or restore the seal

Close the inlet valve and empty the device. Disconnect the

electric supply and close the shut-off valve upstream from the

domestic water inlet. Replace the domestic water shut-off

solenoid valve. Restore operation of the device and perform an

alarms reset
