4. Bolt the cabinet door closed so the pins on the dead bolt
counterpart make contact with the dead bolt assembly. Doing so
should leave two marks of torque sealant or grease on the
assembly where the pins made contact (See Figure 4.1 – Dead
bolt assembly).
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 dead bolt 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 PWM 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)
