8. Fault Finding.

8.1 General

f the air curtain does not operate after running through the

detail provided in Section 10, then a suitably competent service engineer should be called to identify the nature of the fault.

Note The manufacturer operates a service function from the

address provided in these instructions.

All air curtains are tted with fuse protection and motor thermal protection.

Other faults in relation to the element, motor and wiring should be identied using conventional fault nding techniques.

In the event that electrical components are replaced, please ensure that electrical safety checks in accordance with the regulations in force in the country of use are undertaken.

been cleared.

Apart from the communication failure alarm which could be due to a broken connection of the data link and air curtain not found alarm, which could be due to incorrect addressing, all other alarms will cause the base unit to switch o the heater output.

The SmartElec3 base unit is protected from any short circuit on the air sensor or heat sink sensor as the error will cause the temperature to rise and trigger over temperature alarm.

There are ve basic checks to perform should ‘X--’ appear on the program panel display. These are as follows:

1: Continuity: Use a multimeter to check continuity between each end of all four cores at the plugs

8.2 Electrically heated units only.

For the service engineer, please note that there are two thermal cut-outs incorporated in the air curtain which, if tripped, need to be manually reset. The cut-outs are located in the airow near to the elements on the left and right.

Re-setting the thermal cut-out may help to identify the nature of the fault however we do not recommend a re-set without a thorough investigation into why the cut-out operated.

Fig. 13. Thermal Cut-out

2: Short circuit: Use a multimeter to check that there are no short circuits between any of the four cores.

N.B. This test should be done with both ends of the cable disconnected to avoid false readings.

3: Plugs: Check that the plugs are rmly seated on the circuit board in both the program panel and on the base unit.

4: Addressing: (network versions only). If two or more air curtains are networked, check that each base unit has a unique address as described in section 10.2.8.

5: Network cables: Ensure that the total run of all cables in the network does not exceed 110m including the cable to the program panel.

If a panel has never before been run, it automatically starts in engineer’s mode when rst powered-up. To exit this mode, press and hold the button.

Alternatively, the engineer’s mode automatically self-clears after approximately 10 minutes of non-activity on the buttons.

8.3 Standard Controller.

For fault codes refer to SmartElec3 fault table on next page.

8.4 SmartElec3 Controllers.

The SmartElec3 control raises an alarm if any of its inputs are outside their normal working scope. Alarms are displayed on the program panel as a code with a prex “E” . The rst number represents the air curtain address. See chart over.

As the alarms are mutually exclusive, the rst alarm code displayed on the program panel will stay on until the fault has

Doc No. D301021 Page 46 of 64

The system can be reset by powering-up the panel whilst holding down both the and buttons.

The display shows the ‘start’ pattern but then goes blank.

Release the buttons. The display resumes and the system nds only those air curtains which are actually connected and working.

If appears on the display, press and hold the button for a few seconds then release. The display will then return to the normal mode.
