8.4.1.3. 3 - Outs
Screen 1 and 2
Screens 1 and 2 are used to assign each of
the eight relay outputs on the PAK board to an
output type. Refer to
Table 4-3 on page 12 for a
list of output types and their functions.
Note that though the "VSDAnalog" and "Fan
Seq" are selectable output types, these functions
cannot be performed by relay outputs. Do not
assign these two output types to any of the relay
outputs.
Screen 3 and 4
Screens 3 and 4 are used to assign each of
the four analog/digital outputs on the PAK board
to an output type. Refer to
Table 4-7 on page 14
for a list of analog/digital output types and their
functions.
If you are assigning a digital output type (i.e.
any output type except VSDAnalog or Fan Seq),
you must also specify which state (ON or OFF)
corresponds to "active." When the ActiveLevel
is set to ON, the output will be 0VDC when
inactive and 8VDC when active. When the
ActiveLevel is OFF, the output will be 8VDC
when inactive and 0VDC when active.
Screen 5 and 6
Screens 5 and 6 are used to override the relay
outputs and analog/digital outputs. The R1
through R8 fields override relays #1 through #8,
and the A1 through A4 fields override analog/
digital outputs #1 through #4.
To override an output, highlight it with the
cursor and use the POINT "." and MINUS "-"
keys to toggle the field value to either ON or
OFF. To cancel an override, set the field value to
NOR (no override).
Overriding A1 through A4 will set the output
to the DC voltage that corresponds to the
selected digital state. This is determined by the
"ActiveLevel" setting for the output (set in
Screens 3 and 4 under the "Outs" menu). In other
words, if the ActiveLevel of the output is OFF,
and you override the output to ON, the voltage
will be 0VDC while in override.
All overrides initiated with the HHT are can-
celled when the HHT is unplugged from the
MultiFlex PAK.
Screen 7
Screen 7 is used to override the variable-
speed condenser fan output. To initiate an over-
ride, set the Ovrd field to "YES," and specify the
desired output voltage in the Ovrd Volts field.
To cancel an override, set the Ovrd field to
"NO." This override is also cancelled when the
HHT is unplugged from the MultiFlex PAK.
