GENERAL SPECIFICATIONS
Connection
 Internal bus: Via the Installation Base (model: R3-BSx)
 Input: M3 separable screw terminal (torque 0.5 N·m)
 Internal power: Via the Installation Base (model: R3-BSx)
Screw terminal: Nickel-plated steel
Isolation: Input 1 to input 2 to internal bus or internal power
Alarm output: Two outputs per channel available; setpoints are programmable for the speed or the position data by using the R3CON PC Configurator software.
DIP switch settings:
•Input range
•Count Mode
•Alarm Contact Form
•Start Count
(Refer to the instruction manual)
RUN indicator: Bi-color (red/green) LED;
Red when the bus A operates normally;
Green when the bus B operates normally;
Amber when both buses operate normally.
ERR indicator: Bi-color (red/green) LED;
Green in normal operating conditions.
Low-end cutout: 0.1 %
Reset input: Position data reset to ‘0’ when the external contact is closed. (Reset count can be changed using the R3CON PC Configurator software.)
