Malfunction signal
(1) Move the pulse input switch [SW2-2] to the ON
position.(Refer to function settings 1 (Refer to C-73)
"Settings for pulse input".)
(2) Connect the pulse output device (i.e., building management
system) to the external control input terminal block [TM2].
• A pulse width of at least 200 msec will be needed.
• When using PZ-60DR-E, it can be set also from the remote controller.
Connecting methods vary depending on the types of pulse signal
Refer to Section 2 (Refer to C-67) "When the external device
has a charged operation signal of 12 VDC or 24 VDC" or "When
the external device has an uncharged a-contact signal".
(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
using a transmission cable (PVC insulated PVC jacketed
and either between ø 0.65 and ø 1.2, or between 0.3 mm
2
and 1.25 mm in cross section).
(2) Change the setting on the main/sub switch (SW1) on the
second and subsequent Lossnay units to "Sub"
CAUTION:
• Don't tighten screws of terminal block with a torque larger
than 0.5 Nm. It could damage the PCB.
Note:
2
• Up to four 0.3 mm stranded wires or ø 0.65 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.
• When the LGH-150RX and LGH-200RX
5
operate at low fan speed even if extra low fan speed is selected.
Connect to 6 and 7, or 7 and 8 of the monitor output termi-
nal block (TM3) with reference to the wire connection diagram.
Note:
• Don't tighten screws of terminal block with a torque larger
than 0.5Nm. It could damage the PCB.
By-pass or Delay 2 monitor output with delay function 2 can be
possible.
