Series 9130 Operations Manual Rev - 62
Single – This has one relay which works in only one direction to achieve your SP.
Direct - If the PV - SP equals a positive number and the output would bring the PV down toward setpoint
that is direct.
Reverse – If the PV - SP equals a negative number and the output would bring the PV up toward setpoint
then that is reverse
Example: If a 12 mA output drives a 0 degree F temperature (PV)
UP to a 1200 degree F temperature (SP),
this would be REVERSE , and since this would take a SINGLE output from the controller, the Mode for the
Temperature Loop is Single Reverse.
Integral Preset
This field provides an offset for the starting point for PID control, also referred to as “Load Line” or “Manual
Reset”. The range is –100 to 100.
Cycle Time
This field is typically set to the valve travel time multiplied by 1.5. The range is 0 – 300.
Setpoint Change Limit
This is a smart time feature that allows Process Loop to use PB only without Reset until the Process
Variable drops below the percent output set under this category.
It is used to eliminate overshoot.
The Output percentage selected under this category
must be above the normal operating output percentage
of the furnace at heat.
The options are: OFF, 80%, 70%, 60%, 50%, 40%, 30%, or 20%.
Example: If the furnace runs at 40% output at heat for the maximum load, the setpoint change limit should
be set to 60%.
Low Limit
This is the low limit for the loop. The range is –100 to 100.
High Limit
This is the high limit for the loop. The range is –100 to 100.
0 Setpoint Stops Control
If the Setpoint is zero, then all outputs are turned off. The option is either Yes or No.
IN1 high limit shuts down ctrl
If input 1’s high limit is reached, then all outputs are turned off. The value can either be Yes or No.
IN2 high limit shuts down ctrl
If input 2’s high limit is reached, then all outputs are turned off. The value can either be Yes or No.
IN3 high limit shuts down ctrl
If input 3’s high limit is reached, then all outputs are turned off. The value can either be Yes or No.
PID Auto Switch
This is the PID auto switch field. The value can either be Yes or No.
Switch Point PID 1 -> 2
This is the PID Switch Point field. This is used in conjunction with the PV Switching feature. See the
PV
Switching section for more information. The range is –300 to 4000.
Switch Point PID 2 -> 3
