3.14.3 Control Parameters
The control tuning sequence is accessed from the runtime display. Enter the tuning sequence
and make tuning adjustments as follows:
1. Press the Scroll key repeatedly until [TUNE???] appears on Line 6.
2. Press the Up[
∆] key. [CONTROL] appears on Line 6 and [ENT] flashes next to the Scroll
key.
3. Press the Scroll key to start the tuning sequence.
• If a tune password is not required, a 4-letter code identifying the configured
control algorithm type appears on Line 6; go to step 4.
• If a tune password is required, [TUNE] and [PASSWORD] appear on Lines 1 and
2. Use the Up( ∆) key to enter the password number, then press scroll to access
the tune sequence. A 4-letter code identifying the configured control algorithm
type appears on Line 6.
4. Observe the 4-letter code on Line 6. The code letters identify which of the four primary
control algorithm parameters (gain, reset, preact, and manual reset) are active and how
the active parameters are implemented. For example, the code [EOPE] indicates that the
algorithm provides gain on error, reset is off, preact on process, and manual reset is
enabled (see Table 8, Step 8F for more information on Control Type setup).
*
NOTE: The gain, reset, and preact prompts always appear in the tuning
sequence. The tuned values of these parameters are used in the control
algorithm only when their code letters are other than O.
