  • Page 39 Position Retransmit Units To troubleshoot control loop connections: 1. Connect a DC voltmeter across the input and output terminals. For an input current between 4 and 20 mA the voltage varies between 11V and 9 V respective. If voltage exceeds 11 V check that polarity is correct. If the polarity is correct but the voltage is less than 8.05 V, then the current source voltage is not compliant.
