REMOTE ON-OFF
For the input of the remote control terminal CN23
(ON-OFF) and the JR6 quick-release connector
– Remove the JR6 quick-release connector when
using the ON-OFF function;
– When the remote switch is OFF (OPEN), the unit
will be turned off;
– When the remote switch is ON (CLOSE), the unit
will be turned on;
– When the remote switch is opened/closed, the unit
will respond to the request within 2 seconds;
– When the remote switch is ON, the remote/wired
control can be used to select the mode; when the
remote switch is OFF, the unit will not respond to
the remote/wired control request.
When the remote switch is OFF, the remote/wired
control is on, code CP will be shown on the display
board.
– The input voltage is 12 V DC, the maximum design
current is 5 mA.
ALARM
For the input of ALARM connector CN33
– The terminal input is set up for ALARM connection,
but there is no voltage; the power supply comes
from the ALARM system (not from the unit)
– Although the design voltage can withstand even
higher values, we strongly advise connecting a
power supply of less than 24 V and a current of
less than 0.5 A
– If this problem occurs on the unit, the relay will be
closed, thus activating the ALARM
