The Two Lighting Relays controller provides features for cycling layout lighting including timing, delayed timing, random timing, train counting, and day-of-week selection.

Features are arranged in eight "sets," designed to provide a group of selectable features targeted to a lighting application. Features are selected by installing "jumpers" across an array of eight rows by two columns of pins in the upper-left corner of the circuit board.

When the input turns on:

• The relay is turned ON for the jumper selected "ON Time."
• After "ON Time" seconds, the relay is turned OFF and held OFF for the jumper selected "OFF" time.
• After "OFF" time seconds, the relay will again be activated if the input is still ON or when it turns ON.

The 2LR has feature sets for timing from four seconds to twenty minutes and with equal ON and OFF times, ON times longer than OFF times, and ON/OFF times randomly selected within a timing range.

• Equal-ON-and-OFF-Times is useful for designating "day" and "night" lighting cycling.
• ON-Times-Longer-than-OFF-Times provides two different timings by using NC and NO relay terminals.
• ON/OFF-Times-Randomly-Selected cycles lighting on and off without a discernible pattern.

The ON/OFF Timing feature can be activated by a train in an isolated outside-rail track block, by an operator switch, by relay contacts, or it can be made to cycle by applying a continuous voltage to a corresponding input.

When cycling with a feature set with longer ON times than OFF times, a light connected to the relay NO (normally open) terminal will be ON more than OFF; a light connected to the NC (normally closed) terminal will be OFF more than ON.

• The relay is turned ON for the jumper selected "ON Time."
• After the "ON Time" expires, the relay is turned OFF.
• The relay remains OFF until the input is also OFF, then turned ON again. The input must be off after the "ON Time" has expired.

Thus, the relay is ON only once, always for the specified "ON Time," as a train proceeds through a connected track block, a pushbutton is depressed, or connected relay contacts close.

The ONE-TIME-ON Timing feature is useful for synchronizing one light timing with another. For example, morning, evening, or other day-parts are created by wiring the input of a relay jumpered for ONE- TIME-ON Timing to a "day" or "night" relay.

The ONE-TIME-ON Timing feature will not cycle continuously when the input is continuously activated: the input must go OFF before a new timing cycle will be started. Two or more relays set for the ONE-TIME-ON Timing feature can be interconnected to provide "sequencing" functions.

The ONE-TIME-ON Timing feature is available in four feature sets with jumper selecting timing of 2 to 25 seconds, 10 to 130 seconds, 2 to 480 seconds, and 20 to 900 seconds. A delayed form is also available.

Jumpers select counts for the relay from every-other to every- fifth input activation.

The relay stays ON until the next input activation, then turns OFF.

The counter input can be connected to an isolated outside-rail, to count train passings, to an electrical pushbutton, to count button pushes, or to relay NC or NO contacts, to count relay activations.

Lights wired to relay NO terminals will be ON for the selected day, e.g. Monday. A light wired to the NC terminal will be ON for all days except the selected day.

With the "Weekend" selection, a light wired to the NO terminal is on for Saturday and Sunday. A light wired to the NC terminal will be ON for Monday - Friday.
