#810 Thru-the-Ties Delayed-Action Electric Uncoupler Kit - O Scale

Delayed Magnetic Uncoupling

Kadee® #165 Red - Normally Open momentary contact push button switches are recommend.

This package contained one O Scale Magne-Electric electromagnetic, delayed action uncoupler kit, ready to assemble and install Thru-the-Ties. It can be installed on any straight layout track, but especially on mainlines, were false uncoupling my occur.

Operates: 16 volt DC.
We recommend a 16 volt DC power source (at least 2 Amps) or 12-20 volt AC power source (at least 2 Amps) converted to DC with bridge rectifier*. (*bridge rectifier & capacitor not included)

Fits codes 100, 125, 156 and 172 track.

WARNING: Do not use the uncoupler continually. DO NOT activate the uncoupler for longer than 3 MINUTES at one time.
This will avoid possible overheating which will damage the uncoupler.

Delayed Magnetic Uncoupling

Trouble shooting:

Coil Test: Strip off clear insolation on ends of coil wires with a multi meter on the 200 OHM settings check resistance. A good single coil will have a resistance of about 8.8 OHM. A good double coil wired in series will have a resistance of about 17.8 OHM.
If it is much less your coil is shorted and will not generate enough magnetic field to uncouple. (Leaving the uncoupler active for to long cause coil to over heat melting the insolation and shorting out the coil.)

Magnetic Field Test: Before installed in track. With momentary switch activated take a piece of steel and it should sticks across both field plates.
