Typical Auxiliary Equipment Installation
To install auxiliary equipment, an auxiliary elbow drive adapter kit (P/N 13-08821) is required.
The kit contains the English drive elbow (P/N BM4129) and the tape/cable combination (P/N
B7678-106). This has a sprocket sheave that is driven by the English tape/cable combination.
Usually this is installed on the outboard connection pipe elbow.
Note The use of auxiliary units not manufactured or supplied by Varec will void any
Varec warranty and will relieve Varec of any obligation to service the product under war -
ranty.
The perforated tape portion of the tape/cable combination must be seated on the sprocket
sheave throughout the travel of the indicator. The cable portion cannot drive an auxiliary
device. The cable portion attached to the pulley of the half-travel indicator may reach the
gaugeboard connector sheave before a vertical tank is empty if the gaugeboard is mounted
high on the tank.
1. Remove the bolts, cover, and gasket from the elbow.
2. Remove the drive adapter flange bolts, washers, flange cap, and gasket.
3. Install the elbow on the indicator connector pipe.
4. Refer to the appropriate tank configuration installation procedures above and thread the
tape/cable through the elbow. The cable segment attaches to the gaugeboard indicator.
