Catalog 1308242 Issued 3-03 P&B Timer Function Descriptions Repeat: Output relay is turned on at end of programmed time interval which is started by application of input power. Relay stays on for equal time interval, then turns off and cycle is repeated on a free-running basis with equal on and off times until terminated by removal of input power. LED is flashing when output relay is off and on continuously when the relay is on. Applying CONTROL input during LED to show time status. timing will have no effect on timing or the state of the relay. See functional explanation for details. One Shot: Output relay is turned on by applying CONTROL input with input voltage present or application of input voltage with the CONTROL input on. REPEAT Immediately upon either, timing is initiated with the output relay turning off at the ONE SHOT OFF DELAY completion of the selected time interval. Applying CONTROL input after time out INTERVAL will reset the timer, turn on the output relay and initiate another time interval. LED ON DELAY is on continuously when output relay is off and flashes when the relay is on. Applying CONTROL input during timing will have no effect on timing or the state of the relay. Off Delay: Output relay is turned on by applying CONTROL input with input voltage present or application of input voltage with the CONTROL input on. The time interval will be started by removing the CONTROL input with the output relay 3 1 2 S turning off at completion of the time interval. Reapplying the CONTROL during timing will reset the time to zero and inhibit timing until removed. LED is off when CONTROL input is on, flashing during timing and on continuously when the output relay is off. TIME TIME SET 000 TO 999 BASE Interval: Output relay is turned on for a programmed time interval by applying input voltage. LED flashes when output relay is on and is on continuously when the output relay is off. Applying CONTROL input will have no effect on timing or the state of the relay. Time Base: .1 S = 1/10 Seconds Timing Range 0.1 to 99.9 Seconds On Delay: Output relay is off for a programmed time interval which is started by S = Seconds Timing Range 1 to 999 Seconds applying input voltage. LED flashes when output relay is off and is on continuously .1 M = 1/10 Minutes Timing Range 0.1 to 99.9 Minutes when the output relay is on. Applying CONTROL input will have no effect on timing M = Minutes Timing Range 1 to 999 Minutes or the state of the relay. .1 H = 1/10 Hours Timing Range 0.1 to 99.9 Hours H = Hours Timing Range 1 to 999 Hours 10 H = 10 Hours Timing Range 10 to 9990 Hours Dimensions are shown for Dimensions are in inches over Specifications and availability www.tycoelectronics.com reference purposes only.
