Series 70 Electric Actuator Installation, Operation and Maintenance Manual Storage Commissioning Mounting the Actuator Actuators are not weatherproof unless they are properly installed on the valve or prepared for storage. Bray cannot accept responsibility for deterioration caused on-site. • Store units on a shelf or wooden pallet in order to protect against floor dampness. • Cover the units to protect against dust and dirt.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual Wiring the Actuator Setting Travel Limit Switches NOTICE Turn off all power and lockout/tag out service panel before installing or modifying any electrical wiring. 1. Take the actuator cover off. The cover should be kept on hand for reference. 2. Wire the actuator as per the wiring diagram attached to the inside of the actuator cover. NOTICE Power and control wiring should use separate conduit entries.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual NOTICE Setting Mechanical Travel Stops Cam locking screw must be slackened before cam adjustments and re-tightened after cam adjustments. NOTICE If the unit came assembled to a valve, the stops have been factory-set and DO NOT need adjustment. Mechanical travel stops are designed to prevent over travel while manually operating the actuator. They are not designed to stop the electric motor.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual 4. Lock the travel stop bolt in position with the locknut. 5. Manually drive the actuator to the ‘open’ position. 6. Once the actuator is in the ‘open’ position, rotate the handwheel counterclockwise • ½ turn for Actuator Size 003, 006. • 1 turn for Actuator Size 008, 012, 020. • ½ turn for Actuator Size 030, 050, 065. • 2 turns for Actuator Size 130, 180. 7.

Series 70 Electric Actuator Installation, Operation and Maintenance Manual Field or Factory Installable Options Auxiliary Switches Auxiliary switch kits are a field or factory installable option for all Series 70 actuators. Switch kits are comprised of dry-contact (voltage free) SPDT mechanical switches which are used to indicate travel position. Switches are arranged into 2 stacks. For Actuator Size 003 - 065, stack 2 activates 3° prior to switches in stack 1.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual Heater Kit: • Heater with flying leads • Mounting Bracket • #10 Pan Head Screw, Phillips Drive Tools Required: • Screwdriver, 3/16” [5 mm] tip flat blade • Screwdriver, No.1 Phillips Installation Procedure: Turn off all power and lockout/tag out service panel before installing or modifying any electrical wiring. NOTICE Torque switches are not field adjustable. Adjustment of torque switches in the field will void warranty.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual Installation Procedure: • Alternative mounting kit can be ordered in case it is preferred to mount the control station nearby but not on the S70 actuator. Battery Backup Unit Turn off all power and lockout/tag out service panel before installing or modifying any electrical wiring. Bray offers a factory installable Battery Backup Unit (BBU) for the 24 V Series 70 electric actuator.
Series 70 Electric Actuator Installation, Operation and Maintenance Manual Indication of Remote Control Bray offers two field or factory installable kits to indicate if a process controller has remote control of the Series 70 actuator. Remote control of the actuator can be interrupted if the actuator handwheel has been left engaged or if a local control station has been switched out of remote mode. A dry contact (voltage free) mechanical switch provides indication if the handwheel is engaged.
