4. Bolt the cabinet door closed so the pins on the dead bolt counterpart make
contact with the deadbolt assembly. Doing so should leave two marks of
torque sealant or grease on the assembly where the pins made contact (see
Figure 16 on page 36 ).
5. Slightly loosen the adjustment bolts on the counterpart and make the
necessary movements on the counterpart to ensure that the pins align with
the landing plates on the deadbolt assembly. As the amount of counterpart
movement required is an estimate, it may take a couple attempts to
properly align the assembly.
6. Clean the torque seal/grease from the key interlock once finished aligning
the counterpart.
Once properly aligned, the key should turn freely when the cabinet door is fully
bolted shut. If the key does not function when the door is tightly bolted closed,
adjustments will have to be made to the depth of the counterpart. This can be
done by adding shims on the landing plate where the counterpart is mounted.
Resistance Checks Prior to applying control power to the drive, power semiconductor and snubber
circuit resistance measurements must be taken. Doing so will ensure that no
damage has occurred to the converter section during shipment. The instructions
provided below detail how to test the following components:
• Inverter or AFE Rectifier Bridge
– Anode-to-Cathode Resistance Test (Sharing Resistor and SGCT)
– Snubber Resistance Test (Snubber Resistor)
– Snubber Capacitance Test (Snubber Capacitor)
• SCR Rectifier Bridge
– Anode-to-Cathode Resistance Test (Sharing Resistor and SCR)
– Gate-to-Cathode Resistance Test (SCR)
– Snubber Resistance Test (Snubber Resistor)
– Snubber Capacitance Test (Snubber Capacitor)
ATTENTION: Before attempting any work, verify that the system has been
locked out and tested to have no potential.
