237 Maintenance and fault rectificationVEGACAL 62 • For connection to a signal conditioning instrument30317-EN-170503Remove the electronics module. Check the resistance between thetwo plug connections.There must no longer be a connection (high impedance). If there isstill a connection, exchange the instrument or return it for repair1 2 3Fig. 13: Check the resistance in the probe1 Shielding2 Measuring probe3 Ground potentialIn Ex applications, the regulations for the wiring of intrinsically safecircuits must be observed.Depending on the reason for the fault and the measures taken, thesteps described in chapter "Set up" may have to be carried out again.7.3 Exchanging the electronics moduleIf the electronics module is defective, it can be replaced by the user.In Ex applications, only instruments and electronics modules with ap-propriate Ex approval may be used.If there is no electronics module available on site, one can be orderedfrom the VEGA agency serving you.The electronics modules are adapted to the respective sensor. Youcan find a suitable electronics module in the following overview.• CL-E60ZX (without approvals)7.4 Shortening the electrodeThe probe (rod) can be shortened by any length.1. Shorten the rod with a cut-off wheel or metal saw at the lowerend. Make sure the length is correct before shortening.2. Carry out a fresh adjustmentCheck the resistance inthe probeReaction after fault recti-ficationAssignment
