d) Press to write the choice to the controller’s database. The next parameter in
the menu (bIasbIas) will be displayed. Most applications use the default bias value
(zero).
3. Specify the output type for output 1.
a) While still in the menu system, press the key until OutPOutP (output) is
displayed on the top line.
b) Once at the output menu, press to display the output 1 type parameter O1.tYO1.tY
on the lower line.
c) The output type currently assigned to output 1 will alternate with the display of
O1.tYO1.tY. If the output has been changed from the default PidPid, use the or
key to display Pid.Pid.
d) To write PidPid to the controller’s database, press the key once. The next
parameter, O1.ACO1.AC (output 1 action) will be displayed.
4. Specify the output 1 action, dirdir (direct) or rErE (reverse), for output 1. Generally,
heating applications are reverse-acting and cooling applications are direct-acting.
a) When the O1.ACO1.AC parameter is on display, use the or keys to display the
action for your application.
b) Press the key once to write the action choice to the database. The next
parameter, O1.CYO1.CY (output 1 cycle time) will be displayed.
5. Specify the output 1 cycle time.
a) When the O1.CYO1.CY parameter is on display, use the and keys to display

Note 1: The cycle time for analog outputs must be set to 0.2 for the controller to
drive the analog signal properly.
Note 2: “T” outputs directly driving non-inductive loads (small heaters) can have
cycle times as low as 0.2 seconds.
