ETA Systems PS220 Fascicule

OWNER’S MANUAL

SEQUENCING:  When activated, the PS220 CH1 outlet turns “ON”, then CH2 outlet turns “ON”. When deactivated the
PS220 CH2 turns “OFF”, then CH1 turns “OFF.”

DELAY:  A 1, 5, 10 or 30 second time-delay is available between CH1 and CH 2, when turning “ON” or “OFF.”  To adjust
time delays, place the jumper on J100 to the appropriate location. See diagram below.

RESET:  Use the push button switch for resetting the unit’s microprocessor. The Green “POWER ON” LED goes off for

1 second during a manual rest. Use the recommended screwdriver to depress the reset button.

UNIT OPERATION: A Green “POWER ON” LED will indicate when power is present to the unit. (The Green “POWER ON”

LED will go off for 1 second during power up, to indicate the microprocessor is ready.)  Green “POWER ON” LED
will flash while the unit is sequencing on or off, or when another sequencer that is daisy chained in line is
sequencing on or off. The two Red CH 1 and CH 2 LED indicators will light when CH1 or CH2 of the receptacle
is turned on.

DAISY CHAIN: The PS220 is daisy chained to any other PS220 or 4-channel ETA sequencing unit.

Master Unit: connection to the outputs only (terminals 6 & 7). This output connection is then connected to an
input of another ETA sequencing unit.
Slave Unit: connection to the inputs only (terminals 4 & 5). This input connection comes from the  output of
another ETA sequencing unit.
In-line Unit: this unit has connections to both input and output.

Note: the above-mentioned input and output connections can be connected without regard to polarity.
