Need help?Do you have a question about the York SSS 26L-B and is the answer not in the manual?
General safety guidelines for operating, installing, and servicing complex equipment.
Explanation of danger, caution, warning, and note symbols used in the document.
Describes sequence of events when a safety shutdown is triggered by the Logic/Trigger Board.
Shuts down if an SCR output is low for 5 consecutive seconds.
Shuts down if an SCR is detected as shorted under specific voltage conditions.
Shuts down if motor current exceeds 105% of FLA for 40 seconds.
Shuts down if one phase current exceeds 30% of average for 45 seconds.
Shuts down if SCR heatsink temperature exceeds 212°F.
Shuts down if motor current exceeds a programmed peak threshold.
Prevents damage from momentary motor current interruptions.
Shuts down if input voltage exceeds threshold for 20 continuous seconds.
Shuts down if any phase of input voltage drops below a threshold.
Shuts down if any SCR assembly thermistor reads 37°F or lower.
Shuts down if input voltage falls below threshold for 20 continuous seconds.
Prevents starting if SCR temperature exceeds 110°F to avoid failure.
