APPLICATION

This modification is available for center mounted operators models J and DJ.

FUNCTIONS

Provides hand chain operation for manually opening/closing doors with center mounted operator. A reduced drive disconnect chain hoist is connected to the door shaft with sprocket and chain drive. Since the door shaft rotates when the operator runs, the chain wheel is engaged or disengaged by a floor level chain.

CHAIN HOIST INSTALLATION

1. Disconnect power to operator.

2. Install the chain hoist assembly to the wall next to the output shaft. This can be mounted to either side of the output shaft by just moving the 50B12 sprocket to either side.

3. Install the provided 50B35 sprocket onto the output shaft. Align the sprocket with the sprocket on the chain hoist assembly and secure with the 1/4" key provided.

4. Connect the two sprockets together using the #50 chain provided.

NOTE:

The Chain Hoist connects to the door shaft. The chain hoist hand chain does not move until the engagement chain is pulled.

ELECTRIC INTERLOCK SWITCH

1. If an operator is used, be sure to wire this switch into its

control circuit so that the operator cannot electrically engage when the chain hoist is activated.

2. If the operator is set to accept an external interlock, remove the

factory provided jumper between terminals in the electrical box. Terminals 4 and 5 in mechanical operators, and terminals 2 and 3 in logic operators. If other external interlock devices are present connect interlocks in series.

3. If there is no provision for an electric interlock, wire the switch

in series with the stop button.

4. Reconnect power to operator.
