Error Messages - Burkert 8205 Notice D'utilisation

5 MAINTENANCE
Observe safety regulations, when handling acid-containing solutions.
Always rinse electrode with deionisized water and leave for approx. 10
minutes in a 3 molar potassium chloride solution or in tap water.

5.3 Error messages

"ERROR" on the display (except in electrode calibration function) indicates that calibration
data are lost. By pressing ENTER, the user access to operation menu but the device
works with the factory settings (see §5.4). The controller needs re-calibration. If this
message recurs, please return the controller to your supplier.
Temperature: If "----° C" or "----° F" is displayed, temperature is out of range (-40...+150)
or connection with Pt 1000 is interrupted. In this case "PH = --" is displayed. For the
outputs (current and relays) pH=0 is fixed.
pH values out of range: pH>14 or pH<0, "PH = --" is displayed. For the outputs (current
and relays) pH=14, respectively pH=0, are fixed.
Electrode voltage: >+575 mV ou <-575 mV. "PH = --" and "---- m V" are displayed. For the
outputs (current and relays) pH=0, respectively pH=14, are fixed.
Power failure: In case of power failure, the display turns off, 4-20 mA and pulse output to
0, alarm relays open. When the power supply is turned on, the controller is set to the
previous configuration and the measure goes on.
