4.2 Actuator Operation
The Series 70 Actuator can be operated in a Remote mode (DeviceNet control) or a Local
mode (manual control) if the Series 70 has the switch box option installed. If the Actuator does
not operate, depending upon the operating mode, the following are possible causes:
If the Series 70 Actuator is operating in the Remote mode, or if the optional switch box is not
installed (Remote mode is default), verify the following:
1. The Network LED D17 (The network LED should be flashing or solid green indicating
that the S70 is online or commissioned. If the Network LED D17 is red or flashing red, a
Network error is present. Follow the trouble-shooting guide in Section 4.3.
2. Using a DeviceNet Network node commissioning application that can access the Bray
Controls EDS (Section 3.4), first scan the Network and locate the Actuator to be tested.
Open the EDS for the located Actuator and verify the following:
a. "Torque Limit Switch" = "OK"
If the Torque Limit Switch is any value other than “OK”, take the appropriate
steps to clear the fault including clearing any obstructions that could cause the
fault, verify proper operation and adjustment of the Torque Limit Switches, and
check the Torque Limit Switch connections and wiring (Section 2.2).
b. "Local/Remote/Off" = "Remote"
If the “Local / Remote / Off” section indicates “Local” and the Series 70 does not
have a switch box, the S70 is not properly connected. Review Section 2.2 to
correct the wiring fault.
c. "Handwheel" = "Disengaged"
The Handwheel must be completely pushed in for Remote operation. If the
Handwheel does not turn freely with little effort, it is not completely disengaged.
If the Handwheel is completely disengaged but is still reported as “Engaged”, the
S70 is not wired correctly or the Handwheel switch is malfunctioning. Review to
Section 2.2 to correct the wiring fault.
