CUM 740 2.3 Maintenance instructions Every four weeks: Cleaning of the probe: Remove rough deposits at the cable with a cloth. Clean the soiled probe with a brush and soap-suds. ATTENTION: Fact is that the measured value may be impaired by heavy scratches or damages at the measuring windows. -
Page 7: General Description
CUM 740 General description The CUM 740 is controlled by a 16-bit-microcontroller and allows the following functions: l Detection and processing of measured values l Special menu-driven routine with an alphanumeric display l Monitoring of the system and probes l Storage and control of user parameters All user parameters such as measuring range, alarms, cleaning intervals and adjustment of output signals are fed in a menu-driven routine and stored in a battery-buffered memory. -

Page 15: Putting Into Operation
In most cases it is enough to work with a two point calibration, alltough the measurement converter CUM 740 allows to save up to 8 calibration points. The two point calibration happens with tap water (1.measurement point) and with the sludge of the respective application (2.measurement point). -
Page 16: Multipoint Calibration
CUM 740 6.1.2 Multipoint calibration Example putting into operation TS-measurement with CUS 65-A: For a 4-point calibration you will need about 5 liters of activated sludge and 4 Setup procedure: black buckets. The minimum bucket volume for calibration is 2 liters. The first bucket contains clear water for the zero point. - Page 17 CUM 740 MEASUREMENT 1. Press Ö 3x, display shows CONFIGURATION press key E.

- Page 30 CUM 740 Troubleshooting guide Before exchanging the fuses disconnect the device from the mains! Attention Start the device only with inserted and screwed probe plug! Plug in or out the probe plug only when the device is off! Causes of error : Causes for errors in the system may be found at the measuring probe, the measuring transformer, the cable section between both units and in the field of mains supply.
- Page 31 CUM 740 Error messages The signal output “error” is only set when a cause of error exists for at least 10 seconds without interruption. Over-concentration is displayed when the predetermined range end is exceeded more than twice Wrong type of probe is shown when the connected probe does not correspond to the selected type.
