462. The distance between roller 46.1 and angle lever46.8 should be 0.2-0.5 mm when the circuit-breaker is closed.If adjustment is required, release the two bolts46.7 and 46.6.8.5.3 Checking auxiliary switch settings on type Awithdrawable parts(Figure 8/7 )Compliance with the interlock conditions in theareas of the test/disconnected position and theservice position is ensured by auxiliary switch -S6,located in the breaker housing and factory-set.In test operations, the withdrawable part must bemoved by hand with the crank fitted.1. Settings in the area of the test/disconnectedposition• Move the withdrawable part out of the test/disconnected position towards the serviceposition with a few turns of the crank.• Slowly move the withdrawable part back tothe stop.Auxiliary switch -S6 must then operate whenthe hand crank has a remaining angle of ≥ 60oof turn to reach the stop.• Slowly insert the withdrawable part from thetest/disconnected position towards theservice position until auxiliary switch -S6 justoperates.In this position, it must still just be possible tomove closing push rod 11.1. For this test, thefunction of the blocking magnet -Y0(dependent on the order) must be deactivatedmanually.This condition ensures that the electricalinterlock takes effect before the mechanicalinterlock in the motion sequence involved.2. Settings in the area of the service position• Move the withdrawable part out of the limitposition towards the test/disconnectedposition with a few turns of the crank.• Slowly move the withdrawable part forwardsagain to the stop:Auxiliary switch -S6 must then operate whenthe hand crank has a remaining angle of ≥ 60oof turn to reach the stop.8.5.4 Checking auxiliary switch settings on type Bwithdrawable parts(Figures 4/3 and 8/7)Compliance with the interlock conditions in thetest/disconnected and service position areas isensured by position signalling switches -S8 and-S9 located in the withdrawable assembly andfactory-set.In test operations, the withdrawable part must bemoved by hand with the crank fitted with the motorpower switched off.1. Settings in the area of the test/disconnectedposition• Move the withdrawable part out of the test/disconnected position towards the serviceposition with a few turns of the crank.• Slowly move the withdrawable part back tothe stop.Auxiliary switch -S8 must then switch overjust before the stop is reached.• Slowly insert the withdrawable part from thetest/disconnected position towards the serviceposition until auxiliary switch -S8 just operates.In this position, it must still just be possible tomove closing push rod 11.1. For this test, thefunction of the blocking magnet -Y0(dependent on the order) must be deactivatedmanually.This condition ensures that the electricalinterlock takes effect before the mechanicalinterlock in the motion sequence involved.2. Settings in the area of the service position• Move the withdrawable part out of the limitposition towards the test/disconnectedposition with a few turns of the crank.• Slowly move the withdrawable part forwardsagain to the stop:Auxiliary switch -S9 must then switch overjust before the stop is reached.8.5.5 Checking the direction of rotation of the travelmotors on motor-driven withdrawable parts• Move the withdrawable part by hand into acentral position between the test/disconnectedposition and the service position.• Remove the hand crank.• Switch the supply voltage for the travel motor on.• Use the local electrical controls to check that thewithdrawable part moves in the correct direction.Caution:Do not allow the withdrawable part to run upagainst a block when the travel direction isincorrect! Switch the motor power off immediately(the travel process functions electrically by a seal-insystem with limit position switch-off).There may be a danger of injury when the door isopen!8.5.6 Testing of interlock conditions(Figures 7/1, 7/2 and 8/7)The testing procedures for type A and type Bwithdrawable parts are identical.1. The withdrawable part must only be movablefrom the test/disconnected position into theservice position when the circuit-breaker is openand the earthing switch is open.
