Mitsubishi Electric LGH-50RVS-E Installation Instructions Manual page 13

Note
• When connecting multiple cables to the terminal, use round
terminal.
• Solid wire (single-stranded wire) cannot be connected.
• Only one unit can be set as main Lossnay. The operating signal
and pulse signal of the external device can be connected to
Main Lossnay only.
• Connect the power supply cable to each Lossnay unit.
• When setting the Lossnay address for use with a Mitsubishi
Electric Air-Conditioner Network System (MELANS) etc., the
Lossnay with the smallest address in the group will be the
Main Lossnay. When not setting the address, set the address
to "1" for only one unit in the group. The Lossnay with an
address of "1" is the Main Lossnay. (Refer to "Setting the
address" on the section 5 for more detail.)

Signal output from Lossnay unit
Set DIP-SW or Function setting on PZ-62DR-E as following table
depending on the necessary output signal from Lossnay unit. For
more information of signal output, see function settings No.12 to 16 .

• Do not tighten screws of terminal block with a torque larger than 0.5
N ・ m. It could damage the circuit board.
• When connecting multiple cables to the terminal, use round terminal.
• If multiple output signals are necessary, use optional signal output
terminal (PZ-N4GS-E).

CAUTION
• Failure to follow below instructions, it could cause a fire.
• Choose a OA pre-heater which can control the heater outlet air
temperature even both the air flow is maximum and minimum,
and set Lossnay inlet air temperature to 2 - 13˚C.
Otherwise it could fall the supply fan into intermittent
operation.
• Select a duct heater in compliance with local and national laws,
ordinances, and standards.
• Select a duct heater that is tested by a certification body.
• Always select a heater that is equipped with a non-self-
resetting safety device.

• Do not directly supply power from the Lossnay unit to the duct
heater. Doing so could cause fire.
• Install a circuit breaker for the duct heater in compliance with
all applicable laws, ordinances, and standards.
• Install the duct heater separated from the product by a
distance of 2 m or more.
Failure to do so may result in equipment damage due to the
transmission of residual heat from the heater.
• Ensure that the duct heater and Lossnay are wired and that
the Lossnay function settings have been configured, and then
always check operation by trial operation.
• For the duct heater output, see function setting No.61.
When using After-heater output signal, the wiring should be as shown
by the following picture.

For the heater, observe the cautions listed in Pre-heater.

When switching fan speed externally
(when a sensor or other equipment is connected)
Using a field supply sensor, etc., make connection by inserting the
optional remote controller adapter (PAC-SA88HA-E) in the connector
CN17 (Red) as shown by the figure.
Lossnay will operate at the fan speed following the table below,
regardless of the remote controller setting.

n Example "Fan speed 4"
Field supply sensor, etc.
SW1
Use this in such a way that it ventilates at low fan speed normally,
and when the external sensor detects contamination of indoor air, or
SW1 is on, it changes to high fan speed operation.
When multiple Lossnay units are controlled by one input, PZ-62DR-E is
necessary.
The signal has to be inputed into main unit referring to 3.
