5. DRAWING 4. ANTI-TWO BLOCK CIRCUIT

The anti-two block circuit can connect three A2B switches in series. The signal is divided
by a 4.7K

Ω

resistor; therefore, a resistance can be measured 4.7K

Ω

between:

•

console terminal X1:9 and 10

•

junction box terminal 5 and 6

•

the three receptacle connection 1(A) and 2(B) in the junction box.
