3. Configuration changes: setup group, setup pa-
rameter, date & time of the modification, previous
value, new value.
If the description of the previous and/or new value
is too long to be displayed, an index between
square brackets is used. This index indicates the
position of the value in the list of available options
for the parameter. For example, if the Relay 1 mode
is changed from “Control-setpoint 1” to “Con-
trol-setpoint 2”, the recorded event will be “Con-
trol [2]” to “Control [3]”, because “Control-
setpoint 1” is the second option of the list, while
“Control-setpoint 2” is the third.
4. Cleaning events: type of the cleaning action, date
& time of the event.
Note The logged event information can be down-
loaded to a PC through the HI 92500 appli-
cation software.
DIAGNOSTIC MODE
The diagnostic mode allows the user to check if some
errors are still active on the controller, or view the
event log file.
To enter (and exit at any time) this mode, press the
DIAG key. Select the desired option with the up &
down arrow keys, and then confirm the selection by
pressing CFM.
Active Errors
This option allows the user to check which errors are
active on the controller, and therefore provide proper
actions. Each error is displayed together with the cor-
responding code.
Use the up & down arrow keys to scroll through the
complete list, or press DIAG to exit.
If no error is active, the “No error” message will be
displayed.
Event Log File
The event log file contains a maximum of 100 recorded events, which include
errors, calibration events, configuration changes and cleaning events. Use the
up & down arrow keys to scroll through the complete list, or press DIAG to exit.
The event index is displayed on the bottom right corner of the LCD (the oldest
event has index 0, while the latest event has the higher index value).
Each record is complete with the following information:
1. Errors: Error code and
description, starting
date & time, “ACTIVE”
indication if the error is
still active, or ending date
& time if the error is
closed.
2. Calibration events: type
of calibration, date &
time, calibration points
(if available).
