Technical Manual Milk Cooling Controller TARN 1600
Failure Display / Failure Behaviour
Display shows "SEH" and flashes (Sen-
sor Error High), Beeper sounds:
Temperature sensor input is open, wrong
sensor, sensor damaged or cable broken.
Display shows "SEL" and flashes (Sen-
sor Error Low), Beeper sounds:
Temperature sensor cable has short
circuit, wrong sensor or short circuit of
sensor itself.
Display shows "HA" and flashes (High
Alarm), Beeper sounds:
Upper alarm threshold (P12) increased.
Display shows "LA" and flashes (Low
Alarm), Beeper sounds:
Lower alarm threshold (P13) decreased.
Emergency Mode
If the control sensor fails, the controller starts an emergency mode.
Then the refrigeration relay and the stirrer switch ON in a percentage
rate of a total period of 30 minutes, preset by
P04.
E.g.: selecting 40% means 12 minutes on, 18 minutes off.
