Out-of-Range Tolerance

NOTE

If configuration CNF9 is “ON” the unit will shut

down if an out of tolerance condition exists for

over 45 minutes. If configuration CNF9 is “OFF”

and an out of tolerance condition exists, the unit

will continue to operate but generate Alarm 20

(RAS OUT).

The English display for Out-Of-Range Temperature Tol-

erance is “T RANGE.” The code display is FN11. The

choices are A, B or C. A = 3.6_F(2_C), B = 5.4_F(3_C)

and C = 7.2_F(4_C).

When the out-of-range temperature is configured ON

the microprocessor indicates out-of-range when the

temperature has been within the tolerance band at least

once, and then goes outside the tolerance band for

minutes. Also, the unit will shut down.

When the out-of-range temperature is configured OFF

the microprocessor indicates out-of-range when the

temperature has been within the tolerance band at least

once, and then goes outside the tolerance band for

minutes

. Also, the unit will continue to operate.

For set points at or below +10_F (-12.2_C) frozen range

the unit is only considered out-of-range for tempera-

tures above set point.
