Example : a wire break detection installation on switch channel 1
should have a switch connected between terminal 7 (channel 1) and
terminal 29 (0V reference)
The 10k resistor must be connected across the switch, not across the
terminals 7 and 29.
Analogue Input Channels
The control unit has five industrial-standard 4-20mA inputs. These
may or may not be used, and – if used – are displayed on the LCD as
horizontal bars.
Note: An optional expansion card, the AK-6, is available to expand
the number of analogue inputs from 5 to 11. Please see page 27 for
details.
Using Rudolf, all 11 analogue channels can be configured as a 0
-
20mA or 4
-
20mA type.
Channel 1 can be configured as 0-10V.
Note: If channel 1 is used as 0-10V, use a separate shielded cable for
this signal as the 0-10V signal is highly susceptible to noise.
All analogue channels can be customised with text and delays and
whether to issue a Warning, Alarm or Shutdown.
