Note: 1. 50/60 Hz (no selector required) (EUN Series)
Terminals 18 and 19 of EHN/EC-series models must be open when the supply frequency is 50 Hz. These terminals must be
short-circuited when the supply frequency is 60 Hz.
2. Use the G32X-V2K 2-k
Ω
Variable Resistor for external main setting on EUN, EC, and EHN (G32X-V3K 3-k
Ω
for EN-series models).
3. Input 4 to 20 mA or 1 to 5 VDC linear input to the 4 to 20 mA current input terminal.

EC (constant-current model) require
20% min. of the rated current to detect a short mode failure. EC-series models detect an open mode failure if the load current has
dropped to 80% of the rated value. A short mode failure will be detected if the current has risen to 20% of the rated value.
