Function : ON/OFF Version
- Power open, power close. - Stays in position upon power failure. Function : Failsafe version - Power open, power close. Trickle charges battery in either open or closed position. - Actuator driven by battery power to preset failsafe position upon power failure. - Actuator returns to pre-failure position on power resumption. - Failsafe can be either NC (normally close) or NO (normally Open) |

Function : modulating version
- Power open, power close. Actuator movement controlled by input signal (4-20mA or 0-10VDC). - Standard operation : 4 mA or 0V = actuator closed, 20 mA or 10V = actuator open (can be reserved) - Standard operation : actuator closes on loss of control signal, stays put if loss of main power. - Output signal provided as standard (in same format as supply signal) Additional notes (all versions) - Actuator power supply must be on a dedicated circuit and must be grounded. - Isolated dry contact switches are set approximatively 5° ahead of the final motor stop position. Do not use the signal from the isolated dry contact switches to cut the power to the motor, otherwise the actuator will not reach the full open of full closed position. The actuator is designed to have continuously energized power. |

MULTI-VOLTAGE REVERSIBLE ELECTRIC ACTUATOR (12 to 24 VAC/VDC and 85 to 240 VAC/VDC) S4 Led status indicator CONSTANTLY LIT LED If the actuator is operating correctly with no faults, the LED shows a constantly lit light LED FLASHES WITH TWO BLINKS If the actuator has been left in "manual" mode, the actuator's motor runs but doesn't drive the output shaft. After a preset time, the actuator knows that because the torque limiter has not been activated and that the motor is running, it must be in manual.
