Lossnay (PZ-52SF-E).
When using M-NET, the operation
switch of Remote Controller (PZ-60DR-
E), Lossnay remote controller (PZ-
52SF-E) or MELANS is dead.
Does not operate even when the operation
switch for remote controller for Lossnay
(PZ-52SF-E) or MELANS is pressed.

n When an inspection number blinks on the remote controller, follow the procedures shown in the installation and operating manuals
provided with the remote controller.
n If the remote controller is not used, operate after approximately 45 seconds of turning on the power for the Lossnay.

• Check the power supply. (The specified power supply is single-phase 230V ~ 50Hz)
• Check for a short circuit or disconnection in the transmission cable. (Check that the voltage between terminals in the
transmission cables is 9 to 15 VDC for the PZ-60DR-E or PZ-41SLB-E and 20 to 30 VDC for the PZ-52SF-E.)
• Check that the there is 5 cm or more separating the transmission cable from the power supply cable and any other
transmission cables.
• Run the Lossnay independently using the trial operation switch (SW2-1) and check if it runs.
Lossnay runs --> Check the signal lines
Lossnay doesn't run --> Check the power supply
• Check if there are three or more remote controller connected (PZ-60DR-E or PZ-41SLB-E). (The maximum is two.)
• Perform the registration operation using the remote controller for the Lossnay (PZ-52SF-E) or MELANS. (Refer to the
installation instructions for the remote controller for the Lossnay or MELANS.)
• Check the power supply. (Specified power supply: single-phase 230V, wire dia. ø1.6, switch capacity
• Check if the power supply unit is connected or not, and if the power is supplied or not (For a system with Lossnay
only, it is necessary to install the power supply unit.)
• Check the transmission wire for short-circuit or broken wire (Check if DC 20 - 30 V is detected between the terminals
of transmission wire).
• Check if a clearance of 5 cm is secured between the transmission wire and the power cable and other transmission wires.
• Run Lossnay independently to see if it operates properly or not.
Lossnay operates --> Inspect the transmission wire
Lossnay doesn't operate --> Check the power supply
• Check whether or not there is a power supply unit and that the power has been turned on. (On systems with only a
Lossnay, a power supply unit is required.)
• Check if the pulse input switch (SW2-2) is off. (Can be set from PZ-60DR-E)
• Check the overall cable length between the indoor unit or external device and Lossnay. (Refer to technical
publications or other such documents.)
• Check the connections at the external control input terminal block (TM2).
In the case of voltage charged 12 or 24 VDC output device: Connect to external control input terminals 1 and 2.
In the case of uncharged a-contact output device: Connect to external control input terminals 1 and 3.
In the case of Mr. Slim (A control or K control): Connect to external control input terminals 1 and 2.
• Perform the registration operation using the remote control for the air conditioner or MELANS. (Refer to the installation
instructions for the remote controller for the indoor unit or MELANS.)
• Check if the delay has been set.
• Check the overall length of the transmission cable between the external device and Lossnay. (Refer to technical
publications or other such documents.)
• Check if the transmission cable from the external device has come off of the external control input terminal.
Charged 12 or 24 VDC output device
Uncharged a-contact output device
Mr. Slim
• Check, in the case of multiple units, whether the Main/Sub selection switch on the Lossnay unit which is connected to
the external control input terminal is set on the Master setting, and check whether the Main/Sub selection switch on
other Lossnay units are set to Sub.
• Check that the trial operation switch (SW2-1) is set to off.

8 flashes Improper OA temperature (outside the range)
On Operating

Turn the power off and consult your dealer.
Unless the Remote Controller (PZ-60DR-E) or remote
controller switch (PZ-41SLB-E, etc) is used, the lamp
extinguishes (operation stops) 30 minutes later.
Turn off the power and immediately contact your dealer.
