RLS/RSU CONTROL-CIRCUIT CONNECTION:
Current (I) in the control circuit
The limit-switch system is applicable for the currents that follow:
• 45 mA–130 mA at 24 V AC/DC
• A maximum of 100 mA at 115/230/240 V.
RW45 - RLS MOTOR-CURRENT CONNECTION:
Switching capacity of the limit switch at 115/230/240 V AC
A motor-gearbox with a 1-phase electric motor of:
• Maximum 0.09 kW at 115 V AC - 60 Hz or 230 V AC - 50 Hz
• Maximum 0.11 kW at 240 V AC - 60 Hz.
RW241/242 - RLS MOTOR-CURRENT CONNECTION:
Switching capacity of the limit switch at 115/230/240 V AC
A motor-gearbox with a 1-phase electric motor of:
• Maximum 0.18 kW at 115 V AC - 60 Hz or 230 V AC - 50 Hz
• Maximum 0.22 kW at 240 V AC - 60 Hz.
CONNECTIONS AND FUNCTIONAL OPERATION
The RLS limit-switch system has two connecon blocks. Each connecon block has three connecon
terminals. The RSU limit-switch system has a connecon block with twelve connecon terminals.
• Starng point for a correct connecon and funconal operaon is the wiring diagram in §5.5/§5.6
(RLS) or §5.7/§5.8 (RSU).
• Connecon of all safety switches and duty switches is mandatory.
WORKING PRINCIPLE
• The gearbox operates the threaded sha (1) of the limit-switch system through a transmission.
• The connecon nuts (4) move linearly along the threaded sha (1).
• One adjusng screw (a) touches the switching spring (5).
• When a connecon nut (4) is at the end posion, it touches the stopper (6) and subsequently will
turn with the threaded sha (1).
• The adjusng screw (a) moves the switching spring (5) which operates the duty switch (ES11 or
ES12). The motor gearbox stops.
• If a failure of the duty switch occurs, the switching spring (5) operates the safety switch (ES21 or
ES22). This makes sure the motor gearbox stops. It prevents consequenal damage to the system.
