3. 6 2 1 What is a pulse Voltage Pulse on Pin 1 of J1 When connecting to Pin 1 of J2 the pulse must be a voltage that transitions from OV to V and then transitions back to 0V The SSC will wait hang if the voltage stays high without going back to OV after the initial transition from OV to V The value of the V can be any voltage from approximately 2V to 20V Typical voltages are 5V or 12V The value of OV must be below 2V or open circuit ie you could drive this input with a relay that momentarily connects to a 12V source and then provides an open circuit The current required to drive this input is very low milliamps Contact Closure Pulse on Pins 1 amp 2 of JP1 When connecting to Pins 1 amp 2 of JP1 the pulse must be a low resistance metallic contact closure ie relay that transitions from OPEN to CLOSED and then back to OPEN The SSC will wait hang if the contact closure remains CLOSED after the initial transition from OPEN to CLOSED The current passing through this relay is very small milliamps so a low power relay can be used Pulse Width The pulse width can be any value from a minimum of approximately 100mSec to several seconds As mentioned above if the pulse is very long the SSC will wait for the transition back to the normal state before continuing 6 2 2 Starting the PSU with a pulse When the PSU is in Idle State both LEDs off and an externally applied pulse is applied to the Pulse Sta
