For non‑DTS applications: For dual helm installation, a key switch is used at the upper and lower station. The key
switches must operate independently.

For DTS applications: For dual helm installation, a start and stop switch is used at the upper station. The lower station
can use either a key switch at the helm, or a key switch at the main panel and a start and stop switch at the lower helm.
IMPORTANT: For dual helm installation, both key switches used must be modified to operate independently.
IMPORTANT: Cutting the black/yellow stripe wire disconnects the E‑stop circuit incorporated in the key switch. Do not alter
key switches on DTS applications.
• To modify the non‑DTS key switches, cut the black/yellow stripe wire at each key switch and cover both open wire ends
with heat shrink tubing.
