To enter the
I/O Lock
mode and enable a configure value to be entered, click on the I/O Lock icon
on the Tool Bar. Because the values set in Configure are critical to engine operation, it is not safe to
operate the prime mover while these parameters are being configured. In the Configure mode the control
outputs will be set to their off state, and the microprocessor will stop executing the application code. The
control will have to be Reset to continue operation.
The
Reset
icon allows the microprocessor to store the configure parameters, to return the outputs
to their active state, and to resume executing the application software.
When the tuning or setting of parameters is complete, the values must be saved in the control’s
non-volatile memory. Go to the Tool Bar and click the PROM icon for
Save Values
. The values will be
saved in non-volatile memory and will be unaffected by loss of power to the control.
If an application configuration has been previously saved to a *.tc file, the saved set of parameters
can be loaded into the 2301E-HT as a group by selecting the
Load Application Settings
icon.
To save the configuration to a file in the external computer for backup or download later into
another 2301E-HT when a similar system is being set up, select the Save Application Settings icon. All
the tunable values presently set in the control will be saved to a file and can be loaded into this 2301E-HT
control to reprogram it to the saved values or into another 2301E-HT at a later time.
Configure Menu Descriptions
When the user enters on this menu the 2301E-HT hardware will shut down all inputs and then the turbine
will be stopped. Remember that the turbine will stop abruptly.
01 FUNCTION SELECT
The functions that will be used in the 2301E-HT for Francis turbines are selected in this menu.
01 ENABLE CALIBRATE?
[TRUE or *FALSE] When this value is set to TRUE, the Calibrate Mode is
enabled. This value can only be changed in the Configure menus, and Calibrate Mode can only be
operated from the Service menus. The “Start” command is disabled if the control is in the Calibrate Mode.
02 USE BRAKE PERM?
[TRUE or *FALSE] If the Brake Permissive function in the 2301E-HT is going to
be used this value must be tuned to TRUE. The Brake Permissive function closes a relay when the
governor is issued a stop command, the gates are below a preset value, speed and gate position signals
are valid, and the speed is below a preset value.
03 USE AIO LINKNET?
[TRUE or *FALSE] If the external LINKnet HT AIO module is used, configure this
parameter to TRUE.
Pay close attention to the contact ratings on the 2301E-HT relay
outputs. An interposing relay will be necessary for brake permissive
applications.
02A CONFIG ACTUATOR
This menu is used to configure the actuator driver (gate).
01 1=0
–200 / 2=4–20 / 3=0–20
[*2 (1,3)] This integer selects the actuator output current. If the number is
tuned to 1, the software is configured for a 0 to 200 mA actuator driver. If the number is tuned to 2, the
