Bul. 937C Universal Temperature Converter Installation Instructions
S
• Undervoltage lockout: the supply voltage is too low for the outputs to work properly, the outputs
return 0 mA or 0 V, no matter which fault current/which fault voltage has been selected
• Redundancy too large: only if Redundancy active has been selected (see Menu Input Extra section),
if the set maximum deviation is exceeded
• Sensor breakage: see Menu Input section
• Sensor short circuit: only RTD type of sensor; see Menu Input section
• Overrange, Underrange: measured variable outside the maximum measuring range of the selected
sensor (see Menu Output section and Behavior of the current output or voltage output section)
• CJC Error: if the cold junction compensation has been selected (see Menu Input section) and a
breakage or short circuit occurs within the Bul 937A-TCJC terminal
• Input 1: terminals 1 to 3 (also uses terminal 4 for 4-wire resistance measurement);
