8.3 Alarm generation
8.4 Enabling alarms
Error codes causing an alarm can be defined using device_parameters #70
(Alarm_mask) . By setting corresponding bit high in mask defines that error is taken
into account for alarm generation. Multiple errors can be defined by setting mul-
tiple bits high.

All errors generate alarm
Delay prior alarm is triggered from occurrence of bitwise OR of errors and can be
defined from device_params #71 (Alarm_delay) .
When alarm conditions disappears, alarm is switched off after the same de-
vice_params #71 (Alarm_delay) . Watchdog error needs power down of device for
getting cleared.
If device alarm output is triggered, connect to the device using the UI and check
active errors. Below are some checkpoints in case of errors.
SENSOR_RESONANCE_LEVEL_ERR
Check parameters and that measurement signal is ok during material measurement
(above -50 dB). If not, empty resonator surface and check that signal is ok and ap-
prox. -10 dB (see chapter 10.1). Change device.
SENSOR_TEMP_MATERIAL_ERR
Check that material temperature reading is ok, otherwise try changing tempera-
ture sensor. Change device.
SENSOR_TEMP_CERAME_ERR
Check that ceramic temperature reading is ok, otherwise try powering device off,
if it does not help, change device.
SENSOR_ANALOG_OUT_x_ERR
Check that connections and parameters are ok. If connection is not needed, disable
output channel by setting AOx_I_min to -1.
