          Series Features
    Lockout With Random Start T2D Series HVAC/R Timer
    Series Description: The T2D Series provides protection against short cycling of compressors and other motors. At the end of each operation, a lockout delay prevents restarting the compressor or motor until the delay is completed. 24 V AC models can be used with thermostats that include a cooling anticipator resistor. Can be connected in series with the load for delay on make operation.
    Operation: (Lockout with Random Start)
    Connection #1: Upon application of input voltage, a random start time delay begins. At the end of this time delay, the output is energized.

    Lockout Delay: Input voltage must be applied prior to and during timing. When the thermostat or initiate switch opens, the output de-energizes and the lockout time delay begins. At the end of the lockout delay, the output is energized allowing the load to immediately energize when the initiate switch or thermostat closes.
    Connection #2: Upon application of input voltage and closure of initiate switch, the time delay begins. At the end of the time delay, the output is energized and remains energized until power is removed.
    Reset: Removing power resets the output and the time delay.
    • Lockout Delay--Prevents Rapid Recycling of Compressor
    • Random Start Delay--Helps Prevent Low Voltage Starting
    • Delay on Make Timer--Optional Two Terminal Series Connection
    • Totally Solid State 1 A Output
    • 24 V AC ... 230 V AC in 2 Ranges
