Safety Channel Selection DIP Switch Settings
(1)
(1) DIP switches only function when safety channels are used.
Primary Safety Channel
To connect feedback signals to the primary safety channel, set:
S1 sliders to ON
S2 sliders to OFF
S3 slider to ON
Secondary Safety Channel
To connect feedback signals to the secondary safety channel, set:
S1 sliders to OFF
S2 sliders to ON
S3 slider to ON
Primary and Secondary Safety Channels
To connect feedback signals to both the primary and secondary safety
channels, set:
S1 sliders to ON
S2 sliders to ON
S3 slider to ON
