535 User's Manual Chapter 2, Controller Operation 7
BASIC OPERATING PROCEDURES
Use the following as a quick guide to key operating functions of the 535.
To select /change a setpoint
1. Use DISPLAY key to toggle display to SetPoint.
2. Use SET PT key to toggle to active setpoint.
Before the newly selected setpoint is made active, there is a two-second
delay to prevent any disruptive bumps. If the setpoint displayed is
ramping, RAMPING will show the 3rd display.
3. To change value, press ▲ or ▼ .
To change from auto to manual control (bumpless transfer)
1. When in automatic control, press the MANUAL key at any time, except while
in the TUNING mode.
2. The MANUAL key will light in red, and the 2nd display will immediately
change to indicate current output level.
To change from manual to auto
1. When in manual control, press MANUAL at any time except while in the
TUNING or SET UP mode.
2. The 2nd display will not change, and the MANUAL key will no longer be lit
once control changes.
To change manual output values
1. Make sure the controller is under manual control.
2. Use the DISPLAY key to toggle 2nd display to output level.
3. Use the ▲ or ▼ key to change the value.
To override security
If a locked operation is attempted, SECURITY appears in the 2nd display for
two seconds).
1. Use the
▲▲
▲▲
▲ and
▼▼
▼▼
▼ keys to quickly enter the security code, which will show
in the 3rd display. The starting value is 0.
Note: Two seconds of key inactivity will clear the display.
2. If the code is correct, CORRECT appears in the 3rd display. The display
will clear after two seconds, allowing full access.
4. If code is incorrect, INCORRECT appears in the 3rd display. INCORRECT
will disappear after two seconds, and a new security code can then be
entered.
5. The controller will revert back to full security lock after one minute of key
inactivity.
To display control output value
1. Toggle DISPLAY key until the 2nd display shows OUT followed by the output
percentage. This value is the PID output.
• In duplex applications, this value does not directly refer to the output
signal (refer to the Chapter 7 section on Duplex Control for details.)
• For on/off outputs, the output value shown is either ON or OFF.
• For duplex applications with two on/off outputs, the OUT tag is not
shown. In this case, the status of both outputs is shown in the following
manner: 1:ON 2:OFF (1 and 2 are the respective outputs).
NOTE:
See the glossary in Appendix 6 for
explanation of ramping and target
setpoint. Also refer to the applications
in Chapter 7.
