E024 Failure CPG programme
interrupted Control input 87/88 switched: Ext. control
criteria. yes no no
E027 Failure Compressed air failure Pressure below permitted minimum
connection not correct, test: termin. D3/D4
pressure > 2 bar, contact closed: 0 V;
pressure < 2 bar, contact open: 3.2 V. yes no no
E029 Failure Sensor self test error Error detected during sensor self test. Check
sensor. If necessary, replace it. yes no –
E 030 Failure SCS fault reference
electrode 1 Reference impedance too high:
Check reference element and, if necessary replace
reference or combination electrode
For ISFET sensor: leak current > 400 nA. Replace
sensor.
yes no – –
E 032 Failure Outside set slope range for
sensor 1
Sensor aged or defective;
Reference aged, defective or diaphragm blocked;
Buffer solutions too old or contaminated;
PML not in the buffer solutions
yes no – –
E 033 Failure Outside set zero point for
sensor 1 yes no – –
E 034 Failure Outside set offset range
for sensor 1 yes no – –
E040 Mainte-
nance SCC / electrode status of
sensor 1 bad Check sensor, replace if necessary; maybe clean,
(glass membrane blocked or run dry; diaphragm
blocked). yes no –
E043 Mainte-
nance Buffer difference channel
1 too small Wrong buffers used;
Buffer entry incorrect; automatic buffer
recognition defective. yes no –
E044 Mainte-
nance Meas. value channel 1
unstable PML missing; sensor too old; sensor sometimes
dry; cable or plug defective. yes no –
E045 Failure Calibration aborted Repeat calibration and renew buffer solution.
Replace electrode if necessary. yes no –
E053 Failure Failure three-point step
controller reserved yes no no
E054 Mainte-
nance Dosage time alarm Dosage time exceeded at total dosage.
Dosage interrupted, dosing agent empty or
process too inconsistent. yes no no
E055 Failure Display range of main
parameter 1 undershot Measuring line broken,
sensor in air or air cushion in assembly,
Potential matching missing in symmetrical
measurement, static charging in media with
lowest conductivity yes no no
E057 Failure Display range of main
parameter 1 exceeded yes no no
E059 Failure Temperature range 1
undershot
Temperature sensor defective;
Sensor line interrupted or short-circuited;
Wrong sensor type selected
