Page 4: Intended Use
*** To increase operational range to low voltage ОМ-110 has function to disable LED digital indicator if voltage level gets lower than 130V. If voltage level is less than 110V then OM-110 automatically opens its output terminals to initial cold state position and thus tunrs OFF. - Page 5 3.1.4 The wire of the circuit which should be under the device control must be inserted through the hole in the case of OM-110 (item 11; Figure 1). If the limiter is used as the load priority relay, pass the wire that supplies power to both loads (priority and non-priority) through the hole CТ...

To turn ON the power load it’s necessary to take OFF the power supply for the input terminals of OM-110 or to change the position of the autoreclosing time delay (adjustment knob (item 8; Figure 1) to another value different from inF. When moving the autoreclosing time delay knob to the position of prohibited autoreclosing (inF) then on the digital LED indicator is being displayed “inF”... - Page 8 Manufacturer is grateful to you for the information about the product quality as well as comments and proposals concerning the unit operation.
