2.4.3 Query/Programming Mode
The Query/Programming Mode allows for manual programmability and querying of the
programmable functions. This Mode is activated by pressing the “Select Function” push-button.
A function is queried by selecting it using the “Select Function” push-button. The current setting for
the selected function will be displayed on the LED display. The entry in the LED display is edited by
using the four EDIT push-buttons (located just below the LED display.)
The new setting will be implemented into the unit hardware as soon as the entry shown on the LED
display is modified. The unit returns to the Normal mode of operation after 20 seconds of inactivity
(no push-buttons pressed) or after pressing the “Select Function” push-button while the “Monitoring
State” function LED is flashing.
2.4.4 Function Selection
The user selects which function is being programmed by pressing the “Select Function” push-button.
Each press of the “Select Function” push-button will sequentially make one of the “Function LEDs”
blink indicating that the function is selected for programming.
The first press of the “Select Function” push-button selects the function LED that was selected the
last time that the unit was in Query/Programming Mode. The selected Function LED will be blinking
and the current setting will be displayed on the LED display. Each additional press of the “Select
Function” push-button selects the next function (corresponding Function LED blinking) and the
corresponding setting is displayed on the LED display. Pressing the “Select Function” push-button
while the “Monitoring State” function LED is flashing puts the unit immediately back into Normal
mode.
The following functions can be selected for programming: (1) Input Select, (2) ISOTRON Current
Excitation, (3) Sensor Sensitivity, (4) Output Scaling, (5) High pass Filter, (6) Low pass Filter, and
(7) Monitoring State.
When the function is selected, the corresponding “Function LED” will stay blinking until the “Select
Function” push-button is pressed again to select the next function. The LED display will show the
current setting for the selected function. The EDIT push-buttons can then be used to change the
setting. If no buttons are pressed after 20 seconds, then the “Function LED” will stop blinking and
the unit will return to the normal mode of operation (monitoring or non-monitoring state).
Each “Function LED” will remain OFF or ON during the normal mode of operation (and also
immediately after selecting the next function) depending on the setting selected by the user for the
corresponding function.
The user can select a function, and then use the “Select Channel” push-button to view/edit the current
setting for the selected function for each channel.
1. Input Select
This function is used for selecting the type of input to be enabled. The up-down EDIT push buttons
are used to select the input type. The following messages will be shown sequentially on the LED
display each time the up-down EDIT push buttons are pressed: (1) “Chrg”, and (2) “Volt”.
1. "Chrg": Piezoelectric (PE) input is enabled.
2. "Volt": ISOTRON input is enabled.
