10.3 Configurable ESD Overrides
The ESD action may also be configured to override the following:
• Inhibit signals.
• Local and Stop position of the Local-Stop-Remote selector switch.
• Over-torque or valve jammed protection.
• Lost phase protection.
• Motor thermal protection.
c WARNING: Disabling the motor over-temperature, valve jammed or over-torque protection features are permitted,
but by doing so, the user chooses to void the Flowserve warranty and all third-party certifications, including Factory
Mutual, CSA, IECex and ATEX.
10.4 Remote External Interlocks/Inhibits
Three user-defined inputs are provided for the connection of remote contacts that may be used to prevent motorized
operation of the actuator.
These are effective in both remote and local modes and may be overridden by an ESD signal, if so configured.
10.5 Custom Input Mode – Momentary ESD/PSESD (Optional)
The following menus will appear if the customer has the custom mode input option and has enabled custom mode 1 (in
remote control menu).
For custom mode input option and has enabled custom mode 1:
Figure 10.1 - Change Inputs
Following are the preconfigured settings for each input.
Input 0: off, user input, signal present
Input 1: off, PS/ESD enable, signal present
Input 3: on, momentary ESD release, signal present
Input 4, on, momentary ESD release, signal present
Input 5: on, momentary ESD/PSESD, signal present, ESD action close, PS move to target 0%
see Note 4 see Note 5 see Note 6
Note 4: The “ESD ACTION” menu will only appear if the status function for the input is “MOMENTARY ESD/PSESD”.
Otherwise the “SIGNAL PRESENT” menu will return to the “CHANGE INPUTS” menu.
Note 5: The “ESD MOVE TO” menu only appears if position is chosen as action .
Note 6: “PS MOVE TO” menu only appears if the status function of the input is “MOMENTARY ESD/PSESD”.
The user will only be able to change the ESD ACTION (and ESD MOVE TO target if ESD action is position, and the PS MOVE TO settings when in this special custom mode 1.
Following are the preconfigured settings for each input.
