2:
Loosen the “In” terminal for the contact input and insert the positive
contact voltage wire.
3:
Terminate the contact return wire into the negative “-” terminal of
the
24 VDC input. Alternative wiring termination methods may be
required to accommodate multiple terminations.
4:
Secure the screws firmly onto each wire for all terminals.
Connect Output Wiring (Output Interface only)
Terminals accept 24-12 AWG (0.2-4 mm
2
)
1:
Strip 3/8” (9-10 mm) of insulation from each wire.
2:
Determine the type of output required, normally open (NO) or
normally closed (NC), then loosen the respective output and COM
terminals.
3:
Insert the common wire into the “COM” terminal and the output
wire into the respective “NO” or “NC” terminal.
4:
Secure the screws firmly onto each wire.
Set Configuration Mode
The configuration mode switch allows selection between Basic and Custom
configurations of the interface. Basic is the factory default setting.
Basic
Basic configuration mode applies the following default behaviors:
Input Interface:
Inputs control Presets 1-4 respectively, using momentary input mode where
the closure behaves similar to an Echo Inspire station.
• close / open event (push) executes a preset toggle
• holding the contact closed (hold) performs a space raise
• closing the closure twice (in rapid succession) performs a preset
toggle with 1/2 second override timing
Note: Particularly when considering machine driven
applications, ETC recommends a minimum of 500 ms
between any input changes to ensure transitions are
reliably applied.
