Use the listings below to specify sensor input Class, Function and Nomenclature; the S1500 sensor inputs are factory-configured as follows:
Class A: Armed at all times for alarm or shutdown (specify). Class P: Locked out by the Compressor Load lockout timer.
Class B1: Locked out by first lockout timer (First Start/Run timer). ESD: Overrides the Test lockout timer (for Remote/Emergency Stop input).
Class B2: Locked out by second lockout timer (Second Start/Run timer). SD: S1500 System Shutdown Function.
Class C: Armed after fault condition has been cleared for 2 seconds. AL: Alarm Relay Function (no shutdown).
