How
to wire Dayton Off Delay
Timer |
|||||||||||||||||
 Dayton manufacturing in Niles Illinois is owned by WW Grainger |
Push
button that triggers Dayton tining cycle can be any switch or timer Activate push-button switch momentarily Push-button is like a doorbell button, except rated for 120Volts Push button activates Dayton timer Dayton timer turns ON circuit going to load and begins countdown Circuit stays On until countdown is finished Countdown time is 'delay' time When Dayton timer reaches end of countdown, it turns off circuit going to Load The Load (motor, lights, fan) that is controlled by this timer cannot exceed 1 amp. Figure amps for Load: Volts x Amps = Watts Amps = Watts ÷ Volts 200 Watts ÷120 Volts = 1.66 Amps 100 Watts ÷120 Volts = .83 Amps Dayton can directly control 1 - 100 Watt bulb If your Load is greater than 1 amp, you need a contactor or relay. The contactor must have 120 Volt coil. |

Typical pin timer bases Pin timers install on base. Each pin connects to terminal screw. Each terminal screw is independently wired Wiring diagram shows on side of timer. Connect power leads to terminals 2 and 7. Other terminals are dry and receive no power when voltage is applied to terminals 1 and 7. Power going to load connects to terminals 1 and 8. Load wires connect to terminal 3 4 5 6 Terminal 8 feeds into terminals 5 and 6. When timer is OFF, power flows continuously from terminal 8 to terminal 5. When timer is ON power flows from terminal 8 to terminal 6. |

Tork Momentary timers Example Momentary circuit is school bell that rings for 5 seconds. This action can act as push button to activate delay circuit. See Tork 1800 and other mechaical timers and manuals See Tork DGU and other digital timers and manuals |

ICM
201 ON delay timer: Input wire connects to terminal 3 Wire to output connects to terminal 1 When voltage is applied to terminal 3, the delay count begins. When count ends, the circuit between 3 and 1 is closed and voltage flows through timer to the contactor coil. Set the delay time from .03 minutes to 10 minutes. To install: cut Y wire from thermostat. End from thermostat connects to terminal 3. End going to contactor Load connects to terminal 1. ICM 201 timer manual |

On delay timers are
designed to delay start time. Once the LADT2 timer block activates, the countdown begins. When countdown ends, the timer's internal relay activates. When LADT2 relay activates, the NO normally-open contact closes, and NC normally-closed contact opens. For example, when circuit is 'closed' then power travels across terminals and light bulb turns ON. When circuit is open, the light bulb is OFF. NO and NC contacts give two different wiring choices. LADT contacts are 'dry,' and have no power until Hot wire is added to either the NO or NC terminal. Contact block attaches to contactor. When contactor activates, that action activates the LADT2 countdown. LADT series are pneumatic timer attachments. LADT timer is activated by mechanical action of contactor, instead of electric current. Adding timer block, allows the contactor to control additional circuit with time delay. So a second process can begin or stop shortly after contactor activates. |
