OK relay: Ratings at 24Vdc / 120Vac when 5A, variable power of 20W / 600VA. NC contact: having interrupter function. Controller front panel frame reset button: Clears latched alarms and delay normal channels (Timed OK) failed, Woodward, with the "Framework Reset" contact input / output module has the same function. Address switch: to set the rack address 63 selectable addresses. Configuration Keylock: 3500 is used to set the frame in the 'RUN' ("Run") mode or 'PROGRAM' ("program") mode. RUN normal operation mode allows the frame and lock any configuration changes. PROGRAM mode allows the frame to frame and allow normal operation of remote or local configuration.

AC and DC power 3500/15 in two forms, is compatible with worldwide voltage source. It uses a line noise filter as a standard form. Framework can be used in single power supply or when the power does not allow the use of redundant dual power interruption. They are located in the upper and lower frame the leftmost slot. Redundant power supplies can be different voltage source, such as the main power supply from the 120Vac power supply and backup power supply from the uninterruptible power supply 24Vdc. Each power supply can be used alone for the entire framework and its modules. When using a redundant power supply in the form of a frame as a main power source, and the other as a backup, Woodward turbine control, when the main power fails, the backup power supply automatically and immediately form the main power supply module function, to avoid interruption run frame . 3500/15 power supply module has a self-test function, you can monitor whether all of the output voltage meet specifications, and green power module through the front panel "Supply OK" light-emitting diode (LED) display.
