Controls manual
Wiring of remote panel
During the connection procedure
between the electrical panel and the
remote control respect the following
rules:
- do not apply to the analogue and digi-
tal ouputs powers higher than the ones
declared in this manual;
- make the connections respecting the
wiring diagrams in this manual;
- keep the power supply cables diveded
from the control cables to prevent from
interferences.
Analogue inputs
There are 4 analogue inputs:
• 3 NTC temperature probes
• 1 input which may be configured for
an NTC probe or 4...20mA signal.
The inputs are idetified from here on as
AI1…AI4.
Digital inputs
There are 5 voltage-free digital inputs
identified from here on as ID1….ID15.
AI1, AI2 and AI4 may also be added
to these if they are configured as digi-
tal inputs (with parameters Pa H05, Pa
H06, Pa H08).
8 digital inputs are therefore available.
Wiring of remote panel
Important! Never connect the keyboard
when the instrument is on. Avoid short-
circuiting on the cables when the instru-
ment is on: this may damage the instru-
ment.
