Lossnay Remote Controller PZ-52SF-E

Installation Manual

This manual contains only the installation procedure for the Lossnay remote controller. For information about how to wire and install the Lossnay units and the Lossnay adaptor, see their installation manuals. In the remainder of this manual, the term “Lossnay unit” implies the Lossnay with which the Lossnay adaptor is connected unless it is specified. For your safety, thoroughly read

1 Safety Precautions

● The following two symbols are used to denote dangers that may be caused by incorrect use:

WARNING

CAUTION

● After reading this installation manual, keep it in a safe place where the user can refer to it whenever necessary. Make sure that this manual is forwarded to the next user.

Ask your dealer or technical representative to install the unit.

Any deficiency caused by your own installation may result in an electric shock or fire.

Install in a place which is strong enough to withstand the weight of the PZ-52SF-E.

Any lack of strength may cause the PZ-52SF-E to fall down, resulting in personal injury.

Firmly connect the wiring using the specified cables. Carefully check that the cables do not exert any force on the terminals.

Improper wiring connections may produce heat and possibly a fire.

Never modify or repair the PZ-52SF-E by yourself.

Any deficiency caused by your modification or repair may result in an electric shock or fire. Consult with your dealer about repairs.

1 Safety Precautions

described below before installing the Lossnay remote controller correctly.

This symbol denotes what could lead to serious injury or death if the Lossnay remote controller is misused.

This symbol denotes what could lead to personal injury or property damage if the Lossnay remote controller is misused.

WARNING

Ensure that installation work is done correctly following this installation manual.

Any deficiency caused by installation may result in an electric shock or fire.

All electrical work must be performed by a licensed technician, according to local regulations and the instructions given in this manual.

Any lack of electric circuit or any deficiency caused by installation may result in an electric shock or fire.

Do not move and re-install the PZ-52SF-E yourself.

Any deficiency caused by installation may result in an electric shock or fire. Ask your distributor or special vendor for moving and installation.

Restriction when the Lossnay units are connected with the central control-

ler transmission cable

When the Lossnay units and the Lossnay remote controllers are connected with the central controller transmission cable, the number of the Lossnay remote controllers is restricted because of the capacity of the power supply unit. The following table shows how many Lossnay remote controllers can be used. The number of the Lossnay units that isn’t supplied power from the cable doesn’t concern about it.

For details on electrical connections, please refer to the power supply unit catalogue.

(5) Set the Lossnay remote controller address.

Set the Lossnay remote controller address using the rotary switches SW1 and SW2 on the front of the Lossnay remote controller.

■ Setting range: 101 to 200 Rotary switch SW1 indicates the tens digit and SW2 indicates the ones digit.

Rotary switches

In addition, 100 is automatically added to the setting as shown below.

Rotary switch setting 01 - 99 00

Lossnay remote controller address 101 - 199 200

The address is set to 01 when the Lossnay remote controller is shipped from the manufacturer.

CAUTION: The address must be set if the Lossnay remote controller is used as a part of a multiunit system. Set the address

according to its position in the system. In addition, refer to the Lossnay Adaptor Installation Manual for more information concerning the setting of the addresses.

(6) After setting the Lossnay remote controller address, attach the Lossnay remote controller cover.

When attaching the Lossnay remote controller cover, set the top of the cover onto the two top hooks, then push in on the bottom of the cover until it snaps into place. If the bottom of the cover is attached first, the top of the cover cannot be attached. Forcefully pushing in the top of the cover to attach it may break the hooks.

6 Registering the Lossnay Unit With the Lossnay Remote Controller

(Initial registration mode operation)

A Lossnay unit must be registered with the Lossnay remote controller in a group arrangement. Register a Lossnay unit using the initial registration mode as shown below. In addition, the initial registration mode can be used to search for a Lossnay unit registered to the group or to delete a registration.

Setting Procedure

1 Tu rn off the unit.

(Perform the following operation after “H0” flashes on the display.)

2 Hold down both

for more than 2 seconds.

CAUTION

Do not install in any place exposed to flammable gas leakage.

Flammable gases accumulated around the body of PZ-52SF-E may cause an explosion.

Do not use in any special environment.

Using in any place exposed to oil (including machine oil), steam and sulfuric gas may deteriorate the performance significantly or give damage to the component parts.

Wire so that it does not receive any tension.

Tension may cause wire breakage, heating or fire.

Completely seal the wire lead-in port with putty etc.

Any dew, moisture, cockroaches, insects entering the unit may cause an electric shock or a malfunction.

Do not wash with water.

Doing so may cause an electric shock or a malfunction.

Do not install in any place at a temperature of more than 40°C or less than 0°C or exposed to direct sunlight.

Do not install in any steamy place such a bathroom or kitchen.

Avoid any place where moisture is condensed into dew. Doing so may cause an electric shock or a malfunction.

Do not install in any place where acidic or alkaline solution or special spray are often used.

Doing so may cause an electric shock or malfunction.

Use standard wires in compliance with the current capacity.

A failure to this may result in an electric leakage, heating or fire.

Do not touch any PCB (Printed Circuit Board) with your hands or with tools. Do not allow dust to collect on the PCB.

Doing so may cause fire or an electric shock.

Do not touch any control button with your wet hands.

Doing so may cause an electric shock or a malfunction.

Do not press any control button using a sharp object.

Doing so may cause an electric shock or a malfunction.

Never contact the power supply with the control wiring terminals.

Doing so will certainly cause the controller to catch fire.

(2) Purchase the thin-copper wiring pipe and locknuts and bushings separately.

2. Install the Lossnay remote controller.

(1) Pull out about 80 mm of cable from the wall and remove the insulation from its end. (2) Use putty to seal the cable lead-in hole in order to prevent insects from damaging the wiring and to prevent air from condensing on the

Lossnay remote controller circuit board. If the hole is not sealed well, the Lossnay remote controller circuit board may be damaged.
