Maintenance Series 642 7 Maintenance No special maintenance work is required on the device. 8 Trouble-shooting 8.1 Trouble-shooting instructions Always begin trouble-shooting with the following checklists if errors occur after commissioning or during measuring operation. The questions guide you to the cause of the error and the appropriate remedial action. 8.
Series 642 Trouble-shooting Fault code Cause Action/cure Mode1) 209 Device initialization - 0 +1000 Additional errors active Eliminate error displayed 1) The modes have the following meaning: F: Fault, C: Device in service mode, M: Maintenanca required, S: Out of specification, *: depends on mode (F or M). See also section 6.4.2 Supported HART® commands. If several errors are present, the error with the highest priority is output.
Trouble-shooting Series 642 8.2.2 Monitoring the supply voltage If the necessary supply voltage is undershot, the analog output value drops approx. 3 s ≤ 3.6 mA. Error code 19 appears on the display. Then the device attempts to output the normal analog output value again. If the supply voltage remains too low, the analog output value drops again to ≤ 3.6 mA. This prevents the device from constantly outputting an incorrect analog output value. 8.3 8.3.

Series 642 Appendix 10 Appendix 10.1 The Callendar - van Dusen Method It is a method to match sensor and transmitter to improve the accuracy of the measurement system. According to IEC 60751, the non-linearity of the platinum thermometer can be expressed as (1): R T = R 0 [ 1 + AT + BT 2 + C (T – 100 )T 3 ] in which C is only applicable when T < 0 °C. The coefficients A, B, and C for a standard sensor are stated in IEC 60751.
Appendix Series 642 Calculation of β At negative temperatures (6) will still give a small deviation. Van Dusen therefore introduced a term of the fourth order, β , which is only applicable for T < 0 °C.
Series 642 Appendix 10.2 Polynomial RTD With "Polynomial RTD", the sensor is defined by a polynomial (X4*x4+X3*x3+X2*x2+X1*x1+X0) with 5 coefficients. The physical measuring range is 10 to 400 Ω. The 5 coefficients of the polynomial are calculated using the PC configuration software TransComm Light.
