5. TROUBLESHOOTING
In case of problems, always first check with a multimeter whether the following voltages are present:
• between b and a: approx. +24VDC;
• between b and P: approx. +24 VDC;
• between M and P: approx. +24VDC;
• between M and V1 or V2: approx. +5VDC.
A list of possible problems with their causes and remedies is given below.
