FOXBORO FBM202 P0926EQ output module

Manually Stroking the Actuator To enter the manual stroke mode, select Action from the SPC Service Tool menu, then select Manual... An error message is displayed if the SPC is not shut down.The SPC allows the user to enter a manual position demand. Manually stroking the actuator is considered to be a distinct operating mode, and the SPC must be shut down before manual stroking can be performed.Two demand set points provide a means to quickly step between two pre-defined positions for testing the step response of the actuator. The controller dynamics, dither current, etc., can be adjusted on the Dynamics tab of the SPC Service Tool.. Alarm and shutdown settings can be adjusted on the Alarm Setup tab. SPC operation can be viewed on the Overview tab and the Alarms and Shutdowns tabs.

Shutdown (displayed on the status bar)

  This indicates that one or more shutdowns on the Alarms and Shutdown screen are active. This also reflects the state of the hardware Alarm Status output. Analog Position Dmd Out of Range  This fault indicates that the (4 to 20) mA analog position demand current is below 1 mA or above 24 mA.  Type (alarm or shutdown): configurable [If in Alarm state and Analog Pos Dmd Range or Both Analog Pos Dmd Range & DeviceNet Comm Fault signals are lost the SPC will Shutdown]  Latching/non-latching response: configurable

DeviceNet Communication Fault 

 The DeviceNet Communication Fault goes true when any of the following conditions exists: o No DeviceNet master has established communications with the SPC. The DeviceNet Position Demand value is being received slower than a minimum rate specified by the bus master. o The configured MAC ID is the same as the MAC ID of another device already established on the bus. o There is a problem with the CAN bus which is preventing the SPC from communicating. o The DeviceNet master goes into an Idle condition.  Type (alarm or shutdown): configurable if SPC is configured to accept a DeviceNet position demand, status otherwise. When defined as status, it will not generate an Alarm indication on the status bar. [When in Alarm state and DeviceNet Comm Fault or Both Analog Pos Dmd Range & DeviceNet Comm Fault signals are lost - the SPC will Shutdown]  Latching/non-latching response: configurable
