Electrical Hazards and Warnings
Prior to connecting the controller, read the user’s manual for proper connection
and operating information.
Follow National Electrical Code (NEC) safety requirements when wiring and
connecting a power source and sensors or other devices to the controller. Failure
to do so could result in injury, death or damage to equipment and property.
Make sure the proper input voltage is applied to the controller. Improper voltage
will result in damage to the unit.
PC35
Use caution when removing the controller from its case, there may be live voltage
present at the terminals. This should only be done by a qualified technician.
PID Microprocessor - Based

All terminal screws must be tightened securely. Terminal screws not properly
secured can cause an electrical short that may damage property, equipment or
cause injury or death. Terminal screws improperly secured may fall into
equipment causing possible damage to property or equipment.
This instrument is not intended for use in life safety applications.
Important: For applications where physical injury or equipment damage might
occur in the event our product fails, we recommend the installation of
independent safety equipment with its own independent sensor that will shut
down the process.

4.3 CYCLE PROGRAM SECURITY:
4.2 MENU CYCLE PARAMETER ACCESS
The Operation Cycle is the default Cycle and all parameters in this menu can be
accessed using the SETUP key (move forward through the menu) and the BACK
key (move backward through the menu).
The other Cycles can be accessed by pressing and holding the BACK key then
pressing the SETUP key to move through each Cycle. The first item in the menu
of each cycle is shown in the PV display, i.e., the Tuning Cycle displays AtvN in
the PV display and the Alarms Cycle displays FvA1 in the PV display, etc. The
SETUP and BACK keys can be used independently to move back and forth
through the menu after the Cycle is chosen. After moving through the end of the
Cycle menu the controller reverts to the Operation Cycle. The chart on the
following page shows the parameter menu for each Cycle. To move rapidly
through a Cycle menu press and hold the SETUP key.
12
Each menu Cycle can be locked (protected) by pressing BACK and
keys
simultaneously for 3 seconds, a short blink of the display confirms the lock cycle.
Press BACK and
keys for 3 seconds to unlock, a short blink of the display
keys to
and
confirms the unlock cycle. This will alternately lock or unlock the
avoid tampering.
5. CONFIGURATION (PROGRAMMING)
The configuration section gives information on parameter settings in each Cycle
which help to configure the controller for the desired operation. However, the first
parameter that needs to be set is the Input type ( tyPE) in the INPUT Cycle-5
(see 5.5 page 23, and Table 4 page 24). This allows access to those parameters
that operate with the designated input. Output Configuration is the second
parameter that needs to be set (see Cycle-6 section 5.6 page 25, and Table 5).
13
In each Cycle the PV display shows the menu parameter and the SV display
shows the value of that parameter, i.e., avto will be shown in the PV display and
YES or NO will be shown in the SV display. Again, the
and
will change the
parameter value.
PV AND SV INDICATION: The status display shows the present
value of PV (Process Variable). The parameter display shows SV
(Set Point Variable). SV cannot be adjusted if Pr n Ramp &
PV Indication Soak Program is a value other than 0 (zero).
(Red)
The status display shows - - - - whenever PV exceeds the
SV Indication maximum range or there is no signal at the input. In case of
hardware error the status display will show Erro,
Erro where n is the
(Green)
error code number in the SV display. If an erro code number is
displayed, the controller’s hardware is damaged. Consult factory
for repair or replacement.
CONTROL MODE: YES indicates automatic control mode (closed
loop, PID or ON/OFF). NO indicates manual control mode (open
loop). Bumpless transfer from auto ↔ to manual mode is
available. If in doubt program YES.
MANIPULATED VARIABLE VALUE (MV): The upper display
shows PV value and the lower display shows the percentage of
MV applied to the control output. When in manual control (open
loop) the MV value can be manually changed. When in auto mode
the MV value can only be viewed.
PV Indication
To distinguish the MV display from the SV display, the MV is
(Red)
shown flashing intermittently.
MV Indication MV is the percentage of control output, i.e.; if 4-20mA is the
(Green)
control output and 50 (50%) is the value in the SV display then the
output will be 12mA. If a relay (any PWM) is used as the control
output and the Cycle Time ([t) is set for 10 seconds and 50
(50%) is the value in the SV display then the relay will be
ON (closed) for 5 seconds and OFF (open) for 5 seconds.
Pr n
RAMP AND SOAK PROGRAM SELECTION: Selects the ramp

The initial blocking option inhibits the alarm from being recognized if an alarm
condition is present when the controller is first energized. The alarm will activate
only after the occurrence of a non-alarm condition followed by a new occurrence
for the alarm.
Under Pulsed, Delayed, or Oscillator alarm operation the LED’s associated to the
alarms will only light during the actual process state, i.e., when the process is in
alarm situation. The alarm relay, however, will remain closed throughout the time
delay set by the operator. Under Normal operation both the LED’s and alarm
relays will coincide. Figure 13 shows a process with a Pulsed alarm relay where
A1 is the alarm setpoint and T1 is the alarm pulse (0 – 6500s). In this figure the
alarm relay T1 is ON (closed) over a time span that exceeds the actual process
alarm A1 and its associated LED.

The Linear Remote Set Point is a function that enables the operator to change the
set point remotely via a linear signal (0.4Vdc – 2Vdc or 4–20mA). To enable the
use of the RSP, select code 8 (Select Remote Set Point Input) for IO 5 in Cycle-6.
Then connect a discrete input (dry contact) across terminals 9-10 as shown in
figure 15(a) on the following page. A linear input signal must then be connected to
terminals 3-4 as shown in Figures 15(b) or 15(c). The Remote Set Point function
(RSP) is enabled when terminals 9-10 are closed. When this function is used then
the 4-20mA Analog Output (terminals 5-6) cannot be used.

The standard auto-tune procedure is as follows:
• Disable the control output at the rvn prompt in the Operation Cycle (Cycle-1) by
selecting NO.
• Select auto mode operation at the Avto prompt in Cycle-1 by selecting YES.
• Disable the ramp and soak function by setting pr n to 0 in Cycle-1, then program
the setpoint (SV) variable close to the desired process variable (PV).
• Enable auto tuning at the Atvn prompt in the Tuning Cycle (Cycle-2) by
selecting YES.
• Enable the control output at the rvn prompt in Cycle-1 by selecting YES.
During auto-tune the “M” LED flashes. Once auto-tune is complete the “M”
LED turns off.
Note: During the auto tune procedure the soft-start function will not operate and
large oscillations will be induced around the setpoint depending on the process
characteristics. Make sure the process can accept these oscillations and fast
control output changes without being damaged.
The recommended auto-tune procedure is as follows:
•
Follow the procedure above except, program a setpoint 10 – 20% below the
final desired value.
•
After auto-tune is complete (the “M” LED is off) change the setpoint to the final
desired value.
If auto-tuning results are not satisfactory refer to section 7 and Table 6 for manual
fine tuning procedure.
NOTE: Certain processes behave in very irregular manners. In these cases,
control type “On/Off with hysteresis adjust” is recommended.
7. PID MANUAL TUNE
The operator may choose to tune the controller manually for optimum process
perfomance once all parameters are set. This can be achieved by using Table 6
below or by determining the values for the propotional band pb, integral rate ir
and derivative time dt by following the steps on page 30. The procedure on
page 29 should only be done on processes that will not be damaged by large
fluctuations in the process variable (PV).
Table 6 - Suggestions for manual tuning of PID parameters

6. PID AUTO TUNE
During auto tune the process is controlled in ON/OFF mode at the programmed
Set Point (SV). Depending on the process characteristics large oscillations above
and below SV may occur and auto-tuning may take several minutes to be
concluded. The following page gives the standard procedure for auto-tune.

Step 1. Disable all outputs in Cycle-1 by changing rvn to no. Change the
setpoint to the desired process variable (PV) in the Operation Cycle. This value
should be below (PV) if overshoot will cause damage to the process.
Step 2. Make sure pb is set to 0 in Cycle-2, page 15. This places the controller in
ON/OFF control.
Step 3. Enable all outputs by changing rvn to yes in Cycle-1. Once the outputs
are enabled the process variable (PV) will approach and eventually overshoot the
setpoint (SV). At this point the operator should note the following values (see
Figure 18):
The value from the highest point of overshoot to the lowest point of
undershoot, X.
The cycle time of the oscillation, T = cycle repetitions per minute.

Quick Set Up
This quick reference setup is intended to be used by experienced users that
are familiar with the PC35 set up menu or those that need only basic PID
operation. This guide will show how to configure the input, output control
and basic alarm function. For detailed programming information refer to the
Table of Contents to find the required instructions for a particular function.
Follow these steps:
1. Operation: Connect power input to proper terminal connections. After power-
key to move back to Cycle 1. Then press and hold the BACK key and press
the SET UP key once or until atvn is displayed in the PV display. This is the
General Tuning Cycle (Cycle-2). Use the SET UP key to move through the
cycle until sp.a1 is displayed in the PV display. Use the
or
keys to
select the set point for Alarm 1. Press the SET UP key again to move to the
set point for Alarm 2 and do the same. The Alarm(s) are now configured.
7. Auto Tune & Cycle Time: In the General Tuning Cycle use the BACK key to
up the controller is in the Operation Cycle (Cycle-1). See Above Cycle Menu.
Disable all outputs by pressing the SET UP key until rvn is displayed in the
PV display. Press the
or
keys until no is shown in the SV display. The
controller outputs are now disabled. Press the SET UP key again and values
will be shown in the PV and SV displays. To move from one Cycle to the next
press and hold the BACK key then press the SET UP key.
move to the top of the menu to atvn.
atvn This is the Auto Tuning parameter. Use
the
or
keys to select yes in the SV display. This enables the PID Auto
Tuning function. The default for the Cycle Time in the menu cycle is 16
seconds. If a different Cycle Time is required then press the SET UP key until
[t is displayed in the PV display. Change the Cycle Time by pressing the
keys to the desired setting. The controller is now ready for basic
or
process operation.

Program the set point in by pressing the
to increase or decrease the set point to the desired value.
3. Output Control Configuration: From Input Cycle-5 press and hold the
BACK key then press the SET UP key once to move to the Output
Configuration menu (Cycle-6) or until io 1 is displayed in the PV display. Use
the SET UP key to move forward through the I/O’s and BACK to move
backward. There are five optional outputs with the PC35, they include relays,
SSR, pulsed DC, and one 0/4-20mA. Outputs 1, 2, 3, 4, and are designated
for these outputs. Therefore, io 1 to io 4 are the designated outputs for the
relays, SSR, pulsed DC, and io 5 is the designated output for the 0/4-20mA
analog output. If io 1 or io 2 is to be used for main output control then
select code 5 from Table 5 on page 25 for one of the two outputs using the
keys otherwise select 0. If io 5 (4-20mA) is to be used for main output
or
control then select code i2 using the
or
keys otherwise select 0.
9. Enable Process Outputs: Press the SET UP key to display avto and press
or

NOTES:
4. Output Alarm Configuration: Once the output control is configured in Cycle6, then up to 2 alarms can be configured as well. Use Table 5 on page 25 to
configure which outputs will be used for alarms. For example, if io 1 is used
as the main output control then io 2 can be selected for either Alarm 1
through 4 (codes 1 through 4) by pressing
or
keys. The same applies
5
to io 5.
Note: Two I/O’s cannot be configured for the same alarm output.
5. Alarm Functions: After the Alarms are configured for the designated I/O’s
the alarm functions can be programmed. Press and hold the SET UP key to
move rapidly back to the Operation Cycle. Press and hold the BACK key then
press the SET UP key 3 times or until fva1 is displayed in the PV display.
This is Alarm 1 Function. Select the parameter for this function by using the
or
keys. See Table 2 on page 20 for alarm functions. After the 1st
alarm function is selected press the SET UP key to move to the next, fva2
