Note
The fiber-optic cables for the gating boards must be properly inserted in the connectors.
9.4.3.5 Checking the cable and screw terminals
● Check the cable and screw terminals regularly to ensure that they are secure.
● Tighten the screws if necessary. When doing this, comply with the specified torques.
● Check the cabling for defects.
● Replace any defective parts immediately.
9.4.3.6 Inspecting door limit switches
● Inspect the door limit switches regularly for contamination and corrosion.
● Also verify that the the door limit switches function correctly at regular intervals.
9.4.3.7 Checking the cooling circuit
● Check the entire cooling circuit for leaks. If you find a leak in a pipe coupling, tighten the nut
by a ¼ turn
● Compare the measured conductivity value with the permissible conductivity value for the
system (≤ 0.6 µS/cm). You must replace the ion exchanger if this value is close to 1 µS / cm.
● Check the water level in the compensating chamber of the deionized water circuit. If the
level is too low, add some more water. If the level is too high, drain some water until the level
is correct.
