Maintenance; Technical Characteristics - Nice TCE Anweisungen Und Hinweise Für Den Installateur

4) Diagnostics and Signals
TCE has two signalling LEDs which indicate the state of the relays.
Normally, they are "ON". If they are off, this indicates a state of alarm,
meaning that the sensitive device has either triggered or malfunc-
tioned.
State Signalling
Led1: on OUT1: On
Led1: off OUT1: Off
Led2: on OUT1: On
Led2: off OUT1: Off

5) Maintenance

To maintain the guaranteed level of safety of the TCE, regular main-
tenance must be performed at max. 6 month intervals.
!
The maintenance operations must be performed in strict
compliance with the safety directions provided in this manual
and according to the applicable legislation and standards.
6) Disposal
This product is made up of different materials, some of which can be
recycled, such as plastic container, others must be disposed of as
waste, such as electronic board.
1. Disassemble TCE following in reverse order the procedures
described in chapter "Installation".
2. As far as possible, separate all parts that can or must be recycled
or disposed of according to special procedures.

6) Technical characteristics

Nice S.p.a., in order to improve its products, reserves the right to modify their technical characteristics at any time without prior notice. In any
case, the manufacturer guarantees their functionality and fitness for the intended purposes.
Note: All the technical characteristics refer to a room temperature of 20°C (±5°C)

1. Check all TCE parts for wear with special attention to dirt, ero-
sion, rust, overheating.
2. Perform all tests and checks as envisaged in the section "Test-
ing".
3. Sort the various materials and consign them to local licensed
firms for recovery and disposal.
