3. When interlocking with a pulse output
device
(1) Move the pulse input switch [SW2-2] to the ON position.

(2) Connect the pulse output device (i.e., building management sys-
tem) to the external control input terminal block [TM2].

4 . When operating multiple Lossnay units
(1) Connect from Lossnay Unit 1 to Lossnay Unit 2, and from Unit 2
to Unit 3 and so on up to a maximum of 15 units (7 units for types
F1200) using a transmission cable (PVC insulated PVC jack-
eted and either between φ 1/32" and φ 3/64", or between AWG22
and AWG17 in cross section).
(2) Change the setting on the main/sub switch (SW1) on the second
and subsequent Lossnay units to "sub".

NOTE
Up to four AWG22 stranded wires or φ 3/64" PVC wires can
•
be connected to one input terminal.
• For other types of wire up to two can be connected.
• The operation signal and pulse signal can be connected to
the external device of the main Lossnay only.
• Connect the power to each respective Lossnay unit.
5. When switching high/low speed externally
(when CO sensor or other device is
2
connected)
If a commercially available CO
as shown in the drawing, connect by inserting Remote ON/OFF
Adaptor (PAC-SE55RA-E) (sold separately) to the CN16 connector
(for switching between high/low).
* The LGH-F1200RX -E is connected to the lower circuit board.
