Working Modes
P1: Relay activates for OP duration after trigger, then deactivates
P1.1: Subsequent triggers during OP are ignored
P1.2: Subsequent triggers restart OP timing
P1.3: Subsequent triggers reset system (relay off & timing stops)
P2: Trigger initiates sequence: CL deactivation → OP activation → deactivation
P3.1: Cycle: OP on → CL off (LOP cycles settable). New trigger stops cycle
P3.2: Auto-cycle after power-on: OP on → CL off (LOP cycles settable)
P4: Signal hold: Relay on while signal active (timer reset). OP timer starts after signal loss; new signal resets timer
