Installation, Operation and Maintenance 5 - 27
Acceleration Time Out Action
This setting defines the action that th starter will take
if the motor is not accelerated within the maximum
acceleration timer #1 above.
Possible values for action include shutdown;
transition [non-solid state starter types only] (ROM
default); and bypass; [solid state starter types only]
(ROM default). If shutdown is selected, the start will
be aborted upon failure to accelerate. “Bypass” or
“Transition” is the recommended setting, as it will
allow the chiller to start safely in the rare event it
cannot accelerate with the reduced inrush starting
method, however, inrush currents similar to an
“across the line” starting would occur.
EXV Size
Where size(-xx) is the EXV size rating and Trane part
number extension in parentheses as follows:
Table 20
EXV Size
To confirm proper EXV setting, the EXV valve
terminal housing has the valve size stamped on it.
NOTE: if stamped “300,” use setting 300C (-04)
.
External Chilled Water Setpoint Option
Possible values for status are installed or not
installed (ROM default).
External Current Limit Setpoint Option
Possible values for status are installed or not
installed (ROM default).
High Pressure Cutout Setting
The range of values is 5-500 psig (35-3447 kPa) in
increments of 5 psig/kPa. The ROM default is 180
psig (1241 kPa).
NOTE: 6.8948 kPa = 1 psi.
Line Voltage Sensing Option
Possible values for status are installed or not
installed (ROM default).
Unit Line Voltage
This screen only appears if the line voltage sensing
option is installed.
Possible values of [volt] are 180 through 6600 in 5
volt increments. The ROM default is 460 volts. See
the following tables.
