UT4 Sleep Mode is used to extend throttle battery life; it does not charge the throttle batteries but it does reduce the draw on the throttles' batteries.To put the UT4 to sleep, press and hold any function key down and turn any address selector to the next digit. The throttle will go into sleep mode. The UT4 will release the address that was selected and the status light will briefly turn red. If the unit is plugged into LocoNet port you can unplug the throttle and the throttle will then be in sleep mode until plugged back in to LocoNet ...
While it is running as a tetherless throttle, the DT402 and DT400 R and D versions automatically check the power available to the throttle each time a battery is inserted and each time it is plugged into or unplugged from LocoNet. The battery's voltage will be displayed in the text area of the throttle briefly each time the throttle is plugged in or is unplugged from LocoNet. When you plug in to LocoNet the number displayed will be the power provided by LocoNet. This value will be between 9 & 15 volts. Other characters will also be displayed in the LCD depending on ...
For normal tethered operation, DT402/DT400 throttles do not need a battery. If you want to use your DT402/DT400 as an infrared or radio throttle (R & D version), you must install a 9 volt battery. You can use rechargeable batteries.DO NOT USE ANY OTHER TYPE OF BATTERY-AA BATTERIES DO NOT WORK. When you install the battery, the throttle will report the battery voltage and then display Idle. Once you plug in to LocoNet, the throttles will begin operating infrared and Ds and Rs will begin operating as duplex and simplex radio throttles. We recommend that you remove the battery from throttle if it is unplugged ...
My club uses UT4R radio throttles. At the end of the session they ask that the battery be reversed in the throttle housing to "extend battery life". This effectively reverses the polarity of the battery in the throttle. Is this step necessary? Is there any drain on the battery when the throttle is not in use? If there is a drain, should the battery then be removed for storage? So my question is: How should you store a UT4R so as not to drain the battery when the throttle is not being used? The throttle batteries will indeed drain if ...
Keep Alive Power Jack (For DT200 & BT2) When the layout is powered down we recommend that you change the DT200 that is running as the Command Station to Advanced Throttle mode so it can power down and conserve its battery. Do this by pressing Run/Stop & Left Arrow keys together. All other Advanced Throttles on LocoNet will power down and show "idLE" when the LocoNet bus wires (pins 3 and 4 of the RJ12 plug) fall below +5Volts for more than 1/4 of a second. If the RailSync lines on LocoNet (pins 1 and 6 of the RJ12 plug) ...
When your throttle is not in use, we recommend that you store the throttle by removing the battery and putting it back in the battery compartment with the polarity reversed. Be careful here, see Diagram 4 for proper orientation. Although this example is for the DT400, the same caution applies to all other Digitrax throttles. When the battery is placed in the incorrect orientation, the battery terminals short out against the battery tensioning spring (on left), causing the battery to rapidly discharge and get very hot in the process. Correct: Incorrect:
If you break or lose the battery cover for your DT500 series, DT402 series, DT400 series, DT300 series,DT100 series, or UT series you will need a replacement cover. With these throttles being discontinued, we no longer have any battery covers availabe. Serpac produces the throttle case we used. You can order a case through them or other big box electronics warehouses.
