1550ETL / 1650ETL Actuator Option

The Apollo 1550ETL and 1650ETL systems – which use the 835/836 boards – come standard with the 816E / 816EX actuators. These actuators have a gray cable restraint and are considered our “smart” or “intelligent” actuator. These actuators utilize all of the features of the 835/836 board.

Please note that if a 416 (non-intelligent actuator) is to be used on a 1550ETL / 1650ETL system:

1.Switch #10 (SMART ACT.) must be in the OFF position.

2.The “slow start” / “slow stop” feature of the 835/836 board will not work with the 416 actuators.

The rest of the set-up and operation of the system is the same as with the “smart” actuators. For example, limit switches on the actuator must be set before proceeding with the current sensing procedure.

Cable Length of 816E / 816EX Actuators

It is not recommended to lengthen or shorten the cables of these actuators – as they have a sensor in the actuator. Should special length cables be required, they are available by special order in any length up to 50 feet.

If it is necessary to cut the cable, special attention should be given to ensure that proper electrical splices are performed.

Should the cable of the 816E / 816EX actuator need to be pulled thru conduit, it is recommended that the plug be removed, cable pulled, then the plug re-installed. (Specific instructions for this are available from your distributor or Apollo Technical Assistance.)
