Relay Assignments: The Expert-50 can
control up to 32 output relays. The
mapping between the stages and the re-
lays must be determined by the user.
The relays are displayed in groups of 8
relays at a time. The relays assigned to
an output correspond to the flashing
numbers on the display. Press the Edit
key to display each relay state and use
the arrow keys to assign (ON) or
deassign (OFF) the relay. Use the down-
arrow key to step to the next bank of
relays. Use the template at the end of
this manual to map the relays before
assigning them from the front panel. Use the TEST function to test all relay
assignments.
Variable Output Assignments: The Ex-
pert-50 controls two variable outputs
for variable-speed fans. Each fan stage
can use these outputs in variable or on-
off mode. Press the Edit key and set the mode to 'Var' for variable, 'ON'
for ON-OFF or 'OFF' to deactivate the output. Note that the variable out-
puts cannot be configured in variable mode on the last fan stage.
5. Relays with Timer on Fan Stages 2-
15:
For these fan stages, the user can
configure certain relays to operate in
timer mode for cooling while other re-
lays operate in on-off mode. Press the
Edit key and set the timer mode to YES
to configure certain relays in timer mode
for cooling. Press the down-arrow key
to map the relays. If timer mode is set to YES, the user can choose be-
tween ON, OFF and timer when selecting a relay. When a relay is in timer
mode, the digit of the relay alternates with the letter t.
6. Clock Mode on Clock Outputs: The
user must choose between Start-Stop
and Start-Running Time for the clock
outputs. Press the Edit key and use the
arrow keys to configure each output. Press the down-arrow key to map
the relays to the output (see above).
