WARNING INSTRUCTIONS

W ARNING !

READ ALL INSTRUCTIONS

Failure to follow the SAFETY RULES may result in serious personal injury.

INSTALLATION

* GROUND THE RECEIVER CASE. In order to insure safety of the system, the
receiver case must be firmly connected to earth ground.

* PROVIDE A SAFETY CUTOFF SWITCH. If maintenance is required, the radio
must be disconnected from power to prevent accidental activation.

* USE PROPER WIRING. Loose or frayed wires can cause accidental activation of
machinery.

* DO NOT INSTALL IN HOT AREAS. This apparatus can be damaged by heat in
excess of 160 F.

* DO NOT INSTALL IN HIGH VIBRATION AREAS. The life of this apparatus may
be shortened through long exposure to intense shaking or vibration.

* DO NOT INSTALL IN AREAS WHERE WATER OR CONTAMINENTS CAN
ENTER THE RECEIVER. The receiver is enclosed in a NEMA 12 rated enclosure,
however direct spraying of liquids or exposure to caustic environments may result in
malfunction of the unit.

PERSONAL SAFETY

* MAKE SURE MACHINERY IS CLEAR BEFORE OPERATING. Do not activate
the remote system unless it is safe to do so.

* TURN OFF THE RECEIVER POWER BEFORE WORKING ON MACHINERY.
Always disconnect the remote system before doing any maintenance to prevent accidental
operation of the machine.

CARE

* KEEP DRY. If water or other liquids get inside, immediately dry the unit.

* KEEP ANTENNAS CLEAN. Keep antenna connections clean and free of corrosion.

CONSIGNES DE SÉCURITÉ

AVERTISSEMENT !

LIRE TOUTES LES CONSIGNES

Le non respect des CONSIGNES DE SÉCURITÉ peut causer des blessures sérieuses.

INSTALLATION

* RACCORDER LE BOÎTIER À LA MASSE. Pour que le système fonctionne en toute sécurité, le boîtier du
récepteur doit être solidement raccordé à la masse.

* FOURNIR UN INTERRUPTEUR DE SÉCURITÉ. Lors de travaux d’entretien du dispositif, déconnecter le
poste radio afin d’éviter une mise en marche accidentelle..

* UTILISER LES FILS APPROPRIÉS. Des fils découverts ou usés peuvent provoquer un démarrage accidentel
de la machinerie.

* NE PAS INSTALLER DANS DES ENDROITS CHAUDS. Des températures supérieures à 160 °F (71°C)
peuvent endommager l’appareil.

* NE PAS INSTALLER DANS LES ENDROITS SOUMIS À DE FORTES VIBRATIONS. L’exposition
prolongée de cet appareil à des vibrations ou des secousses intenses peut en réduire la durée de vie.

* NE PAS EXPOSER LE RÉCEPTEUR À L’EAU OU À TOUT AUTRE CONTAMINANT. Bien que le
récepteur soit entouré d’une enceinte répondant à la norme NEMA 12, l’exposition directe à un liquide ou à un
environnement caustique peut entraîner un mauvais fonctionnement de l’appareil.

SÉCURITÉ

* S’ASSURER QUE LA MACHINERIE EST DÉGAGÉE AVANT DE LA FAIRE FONCTIONNER. Ne pas
faire fonctionner le système de téléguidage à moins que cela puisse être fait en toute sécurité.

* METTRE LE RÉCEPTEUR HORS TENSION AVANT D’EFFECTEUR DES TRAVAUX SUR LA
MACHINERIE. Afin de prévenir la mise en marche accidentelle de la machinerie, toujours débrancher le système
de téléguidage avant de d’effectuer des travaux d’entretien.

ENTRETIEN

* GARDER AU SEC. Sécher immédiatement l’appareil, s’il est exposé à de l’eau ou tout autre liquide.

* GARDER LES ANTENNES PROPRES. Garder les raccordements d’antenne propres et exempts de corrosion.

SECTION 1: SYSTEM DESCRIPTION

1.1 INTRODUCTION

The Remtron

Radio Remote Control
Systems are designed for control of industrial rated
machinery. This system complies with requirements for
operation under part 15 of the FCC rules and regulations.
This means neither the operator nor the company need
apply or register for a license to operate this equipment.

The basic system consists of a transmitter and a receiver.
The transmitter sends commands to the receiver by means
of radio waves in the 900 MHz band. Receivers operate
from 115 VAC 50/60 Hz power. Operation from 220
VAC is also available.

1.2 TRANSMITTER DESCRIPTION

The

hand held transmitters are housed in
rugged cases molded from a modified polymer plastic
that stands up to extremely rugged use. A key feature of
the hand held transmitters is Remtron's patented switch
assembly for control inputs. This long life elastomeric
keypad is ergonomically designed to provide easy
operation over long periods of time with exceptional
reliability.

The

lever and joystick transmitters provide
rugged yet lightweight housings that allow daylong use
without a strain on the back.

power for the 21T10 or 21T14 transmitters for a month's
normal use. Other transmitters contain additional batteries
for even longer operating time between battery changes.
An additional feature automatically shuts the transmitter
off after a preset time interval of inactivity to further
extend the battery life.

Refer to Section 5 for details on the specific transmitter
supplied with your system.

1.3 RECEIVER DESCRIPTION

The

receivers consist of two
subassemblies, an RF/Decoder board and a Relay board,
mounted inside a NEMA 12 cabinet. They are equipped
with two safety relays in addition to the control relays.

RF/Decoder Board

The RF/Decoder Board contains the Radio Receiver
and the Microprocessor based control system. Signals
are received by an advanced synthesized RF module
that operates in conjunction with the microprocessor.
Commands are received on one of 87 possible
frequencies and are checked against a 16 bit address
code for proper identity and further tested against a 16
bit CRC check code. This insures only valid information
meant only for the particular unit is decoded.

All the transmitter functions are controlled by a
microprocessor with a special memory for configuration
information. This offers a great degree of capability and
versatility while at the same time providing simplicity of
operation and maintenance.

The antenna is internal to most transmitter cases, protecting
it from damage. An indicator LED provides a quick
visual check of the transmitters status.

The transmitter sends data at two rates. When a switch
is pressed or released, three rapid commands are
generated to insure a fast system response. The transmitter
then reverts to a 1/3 rate to conserve battery power.
The crane control transmitters are designed to be very
efficient. Only two AA batteries are needed to provide

The microprocessor contains a nonvolatile memory that
retains the frequency, address and particular operating
parameters for the system. The receiver is programmable
by means of PC compatible computers equipped with
an RS-232 serial port or by an independent programming
unit.

Relay board.

The Relay board contains the output relays and the power
supply. Two (2) relays form part of the safety system.
All outputs include spike snubbers to remove transient
voltages from the control lines.
For convenience, the interface terminal strips are un­pluggable. The relay board can be easily removed without
the necessity of tracking wire numbers and positions.
