EK-1312, "HI PRESS SAFETY INJ MOV OVERLOAD"

EK-1312, "HI PRESS SAFETY INJ MOV OVERLOAD"

Sensor

49-137, 49-197, 49-151, 49-157,49-237, 49-241, 49-257, 49-261, 49-2113, 49-2213, 49-2313, or 49-2413

The thermal overload does not interrupt power to the MOV. Due to wiring configurations for the following valve pairs, alarm will not reflash if one MOV of the pair is in alarm and the second MOV of that pair goes into alarm:

  • MOV-3068 and MOV-3082;
  • MOV-3066 and MOV-3080;
  • MOV-3062 and MOV-3081;
  • MOV-3064 and MOV-3083.
