4.3.6 Device Programming P707 (PC menu only)
Entering parameter P707 = 1 will delete all data in EEPROM. The device will then expect
to receive a new identification ID, 20 constants, 200 programming steps and a CRC
(checksum) following data transmission.
Once data transmission has been completed successfully data are copied to EEPROM
followed by an echo of 0. Otherwise 1 is echoed. The PC program will control data
transmission and the generation of the CRC.
4.3.7 Test parameters
Test parameters are used for electrical device checks.
Check analog inputs and push buttons (ONLINE)
Check calibration data (ONLINE). Both microprocessors contain calibration data about
the redundant analog inputs assigned to them.
4.3.8 Calibration
Devices are calibrated ex works. Therefore recalibration is not normally required after
commissioning. An annual check is regarded as being sufficient. Range changes or live/
dead zero changes do not involve recalibration.
Recalibration is also not required after changing from current to voltage inputs or vice
versa (also 5V ... 10V) because precision resistors have been used.
Set the MODE jumper to PROG (4–5) and the TEST jumper to X2. Connect the device
to the PC using the TERMINAL EMULATOR <ALT><E> (see section "Numerical
parameter list").
1. Set all analog inputs to 100 %
2. Enter P790=1 (calibrate analog inputs)
3. Display P790 = n
n = 0 o.k.
n = 1...8 error in channel n
n = 9 jumper TEST disabled
