Remote Cascade Enable Logic There are three different options for enabling Remote Cascade Setpoint and Cascade control as follows: • One Remote Enable contact input or function key command • Both enable commands programmed; Remote Casc Enable and Cascade Enable • No enable commands programmed When only one Remote Enable command is programmed (either F-key or contact input), selecting ‘Enable’ will enable both Cascade control and Remote Cascade control. This configuration allows both functions to be enabled with one command if this is the normal operation mode. If ‘Disable’ is selected, both control modes are disabled. A contact input can be programmed to enable and disable the Remote Cascade Setpoint (RCS) input/function. When this contact is open the RCS is disabled, and when it is closed the RCS is enabled. The contact can be either open or closed when a 505E trip condition is cleared. If the contact is open it must be closed to enable the RCS input. If the contact is closed, it must be opened and re-closed to enable the RCS input. When both Remote Cascade Enable and Cascade Control Enable commands are programmed, each function is enabled by its respective command selection. If Remote Cascade Enable is selected, only the Remote Cascade Setpoint will be enabled. If Cascade Control Enable is selected, only Cascade control will be enabled. If Remote Cascade Disable is selected, only the Remote Cascade Setpoint will be disabled. If Cascade Control Disable is selected, both Remote Cascade control and Cascade control will be disabled. However, if before the Cascade PID was ‘In-control’, a Cascade disabled command is given, only Cascade control will be disabled. If no external contact input or function keys are programmed for the ‘Enable’ commands, Cascade Control and Remote Cascade Control must be enabled from either the front panel keypad or from Modbus. Since the front panel and Modbus provide both Remote Cascade Enable and Cascade Control Enable commands, they will operate in the same manner as ‘both enables programmed’. Refer to Volume 2 of this manual for information on related Service mode tunables. All pertinent Remote Cascade control parameters are available through the Modbus links. See Chapter 6 for a complete listing of Modbus parameters.
