Location Alarm Alarm name default*1
DO Device status SENCOM comm. error *3 F
Measure alarm Temperature too high S
Temperature too low S
DO too high S

Calibration Due N
Sensor membrane failure N
*2: Latest revision does not support script, or arithmetic by multiple sensors.
*3: After power on, when no single communication is established with SENCOM SA on sensor connection number, this error is
sensor type, because FLXA402 can identify sensor type automatically.
*4: Wash recovery alarm stays on until another wash starts. Set the alarm to OFF, if you need.
CAUTION
Do not cancel error settings if the cancellation may cause hazards.
NOTE
The “Impedance 1 too high/too low” and “Impedance 2 too high/too low” alarms are displayed in
the Error setting. In general, for a pH sensor, “Impedance 1” represents “glass electrode,” and for
an ORP sensor, it means “metal electrode.” “Impedance 2” represents the reference electrode in
all cases.
The “Impedance 1 too high/too low” and “Impedance 2 too high/ too low” errors apply to sensors
with liquid earth. Sensors with liquid earth include PH8EFP, PH8ERP, PH8EHP, OR8ERG,
OR8EFG.
include HA405, HA406, DPA406, DPA405, DPAS405, HF405, HA485, DPA485.
For measuring a solution with low conductivity such as pure water pH measurement, set the

OR8ERG or OR8EFG, doesn’t have any temperature element, set both of “Temperature too
