Thank you for choosing M-System. Before use, please check contents of the package you received as outlined below. If you have any problems or questions with the product, please contact M-System’s Sales Office or representatives. ■ PACKAGE INCLUDES: RTD input alarm module ....................................................(1) ■ MODEL NO. Confirm Model No. marking on the product to be exactly what you ordered. ■ INSTRUCTION MANUAL This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures. POINTS OF CAUTION ■ CONFORMITY WITH EU DIRECTIVES • The equipment must be mounted inside the instrument panel of a metal enclosure. • The actual installation environments such as panel con- figurations, connected devices, connected wires, may af- fect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conform- ity. ■ HOT SWAPPABLE MODULES • Replacing the module does not affect other modules on the same base. Thus, the module can be replaced while the power is ON. However, replacing multiple modules at once may greatly change live voltage levels. We highly recommend to replace them one by one. ■ GENERAL PRECAUTIONS • DO NOT set the switches on the module while the power is supplied. The switches are used only for maintenance without the power. ■ ENVIRONMENT • Indoor use. • When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation. • Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact. • Environmental temperature must be within -10 to +55°C (14 to 131°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation. ■ WIRING • Do not install cables close to noise sources (relay drive cable, high frequency line, etc.). • Do not bind these cables together with those in which noises are present. Do not install them in the same duct. ■ AND .... • The unit is designed to function as soon as power is sup- plied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet. INSTALLATION Use the Installation Base (model: R3-BSx).

Unused channels left open are equal to the burnout, which turns the red ERR LED on and sets a burnout flag at the PLC or the host device. Connecting the resistor means approx. 0°C. An alarm setpoint must be set to a value that does not trip an unwanted alarm. Unused channels can be specified and set so on the PC Configurator Software (model: R3CON) without needing to connect resistors at the field terminals.

High alarm: An alarm is set when the input signal goes above the setpoint. Low alarm: An alarm is set when the input signal goes be- low the setpoint. ■ DEADBAND (HYSTERESIS) (0.00 to 100.0°C or 0 to 1800°F; factory set to 10.0°C or 100°F) Deadband (deviation between the points where the alarm is set and reset) is selectable for each alarm trip point. ■ POWER ON DELAY TIME (0.0 to 99.0 seconds; factory set to 5.0) The alarm output start functioning in the preset time after the power has been turned on. This setting is common to all four points. ■ ALARM ON DELAY TIME (0.0 to 99.0 seconds; factory set to 1.0) The alarm output is set when the preset time elapses after the input has entered in the alarm range. This setting is common to all four points. ■ ALARM HOLD TIME (0.0 to 99.0 seconds; factory set to 1.0) The alarm output is held for the preset time even if it is reset in shorter time. This setting is common to all four points. OUTPUT DATA DESCRIPTIONS Four alarm setpoints are selectable per each input. One (1) word (16 bit) data is transmitted to the PLC or the host device via the R3 network module. 0 15 Alarm 1 Alarm 2 Input 1 Alarm 3 Alarm 4 Alarm 1 Alarm 2 Input 2 Alarm 3 Alarm 4 Alarm 1 Alarm 2 Input 3 Alarm 3 Alarm 4 Alarm 1 Alarm 2 Input 4 Alarm 3 Alarm 4 WIRING INSTRUCTIONS ■ SCREW TERMINAL Torque: 0.5 N·m ■ SOLDERLESS TERMINAL Refer to the drawing below for recommended ring tongue terminal size.
