FLOATING (ME4640-60 and ME4640-30)Two inputs are used - one for Close (brown wire) and one for Open (redwire) commands. Both inputs are similarly configured either by external relaycontact, or solid state device (triac). A network is connected across the inputto assure adequate holding current for the triac (<10Ma). The input is normallybiased low, receives AC line for valid input.The input de-bouncing requiresa signal duration of not less than 0.1 seconds to register as valid.
The total range of the valve opening or closing signals is 60 seconds for theME-4640-60, divided into 30 x 2 second pulses, or 30 seconds for the ME-4640-30, divided into 15 x 2 second pulses. Input activation is recordedcumulatively and algebraically, until the signal time exceeds 2 seconds (i.e. Opendirection pulses accumulate and Close direction pulses subtract until a > 2second time is registered). The motor then steps 1/30th or 1/15th of the 4mmtravel.
Actuators self test is not required. On power up if the actuator receives aclosed position signal it will start stepping and will continuously drive until theclosed position is reached if a 60 seconds or 30 seconds signal is accumulated.
ME4640-60
Signal input: .........................0.1 to 60 seconds in either direction, inputs shorter than 0.1 seconds are ignored
Number of steps:..............end-to-end 30
ME4640-30
Signal input: .........................0.1 to 30 seconds in either direction, inputs shorter than 0.1 seconds are ignored
Number of steps:..............end-to-end 15
COMMON TO ME4640-60 & ME-4640-30
Input polarity: .....................Input to 24Vac line (+/-10%)
Input Impedance/current: ...................................2KΩ or 12mA RMSSwitching:..............................low energy (gold) dry contacts or solid state (triac).
If triac is used the controller has to be 24Vac linefired (GROUND FIRED TRIAC IS NOTACCEPTABLE).
Dead Band:...........................0.12 seconds
Interlock: ...............................if both inputs are energized simultaneously, no movement results
