4.1.2.7 Static Function Selection with Watchdog Daisy Chain
This operating mode is selected by setting menu item 200 to 6 by choosing Mode 6: Static
Function Selection with Watchdog Daisy Chain from the General Configuration form of the
PC Interface.
In this operating mode, Program Block 1 is always active and the program defined in menu
210 is used. Program Block 2 is always inactive and menu item 211 has no function.
The digital input is passed through the module into the digital output. In this way, one single
watchdog timer can be used for a number of EPC modules. One EPC module would need to be
configured for Mode 1 (Dynamic Function Selection with Watchdog Monitor) while the
remaining EPCs would be configured for Mode 2. Any module failure would break the daisy
chain.
4.1.2.8 Static Function Selection with Limit Monitor
This operating mode is selected by setting menu item 200 to 7, by choosing Mode 7: Static
Function Selection with Limit Monitor from the General Configuration form of the PC
Interface.
In this operating mode, Program Block 1 is always active and the program defined in menu
210 is used. Program Block 2 is always inactive and menu item 211 has no function.
The digital output provides a signal as to whether the stroke command is being limited due to an
over-Power or over-Pressure condition. The over-Power condition is specified from the
Horsepower Limiter. The only supported over-Pressure condition is specified by the Flow with
Pressure Limit Control algorithm (Generation 2).
If either limiting condition is taking place, the digital output will be low (0 VDC). If no limiting
situation is taking place, the digital output will be high (V
Supply
). If the Horsepower limiter is
disabled and a program other than a Flow with Pressure Limit Control program (Generation 2) is
active, the digital output will be high.
