Signal controller 2286
• Multiple functions
• Programmable from front
• 3-digit LED display
• Analog or Pt100 input
• Relay outputs
• Max. 50% offset
Application
PID on/off controller, PI step controller or 3-band controller with analog or Pt100 input. As trip amplifier with setpoint
adjustment through external current / voltage signal with neutral zone surrounding the setpoint. Especially suitable in
applications where easy 11-pole relay socket mounting is required for instance in a panel. Possibility for readout of process
data through the built-in display.
Technical characteristics
The 2286 is microprocessor-controlled and basic-calibrated. This means that the input and output can be programmed acc. to
the requested signal range without any re-adjustment. Thereby a high degree of accuracy and flexibility are ensured. The
output consists of two relays with a make contact connected to a common point. The user interface consists of a 3-digit
display and 3 function keys in the front. The interface is used to change a function or an input signal range.
Inputs
Analog inputs - 2286A
The A and B channels can be freely programmed via the front keys and JP1 and JP2 to current in the range 0...20 mA or voltage
in the range 0...10 VDC with a max. offset of 50% of the actual max. value.
Pt100 input - 2286B
Linearized Pt100 temperature input in the range -99...+850 °C with 3-wire connection. The temperature range can be scaled
via the front keys. Max. offset is 50% of max. temperature, min. span is 50°C.
Functions
PID on/off controller
Accurate setting of the regulation parameters XP (proportional band), TI (integrating time) and TD (differentiating time), with
the units selected as XP %, TI s and TD s. Minimum XP is 0.01% equivalent to a gain of 10,000. By setting TI and TD to 0, the
function will be a pure proportional controller. The controller adjusts the time interval between the pulses on the output, the
pulse width is set by the parameter TP. When the process value is outside the proportional band, the output gives a constant
up / down signal until the process value is brought within the proportional band. Hereafter the output pulses with a variable
interval depending on the distance from the setpoint. The neutral zone is an accepted deviation in relation to an ideal output
value, where no function is required on the output. The neutral zone is set in %. The setpoint can be selected as internal
(external setpoint input disabled) or as external (current / voltage).
PI step controller
The PI step controller is especially suitable for control of motor-driven
valves, throttle valves and dosage units. When the process value is outside the proportional band, the output will give a
constant up / down signal until the process value is brought within the proportional band. Hereafter the output pulses with a
variable OFF time depending on the distance from the setpoint. A selected minimum ON time protects the motor against too
short activations.
The regulation parameters are XP (proportional band), tAU (exponential average time of the active relay state) - functions as
integrating time, tP (the shortest active time of the relays) and nEU (neutral zone) - the band that the process is to be kept
within. The setpoint can be selected as internal (external setpoint input disabled) or as external (current / voltage).

8 2286V102-UK
3-band controller
The neutral zone is an accepted deviation in relation to the setpoint where no function is required on the output. The neutral
zone is set in % of the input span and centered around the setpoint. If the process input drops below the neutral zone, the UP
relay is activated until the process input rises to the setpoint value. Similarly the DOWN relay is activated if the process input
rises above the neutral zone, and releases when the input signal drops to the setpoint value. The setpoint can be selected as
internal (external setpoint input disabled) or as external (current / voltage).
dl/dt function
The function monitors the size of the decrease or increase (dl) of the input within a set period of time (dt). If the set ratio, i.e.
change per time unit, is exceeded, the relays will be activated. A time constant can be selected for the averaging of the input
value.
Comparator with an external setpoint
The process value is compared to the external setpoint, and if the two signals differ, a relay will be activated, i.e. the UP relay
for process values larger than the setpoint plus a ½ neutral zone, and the DOWN relay for values below the setpoint minus a ½
neutral zone.
Trip amplifier with an external setpoint
The relay function can be selected for increasing / decreasing or window. As a trip amplifier the relays can be activated
individually when the input value differs from the setpoint plus or minus the neutral zone. The window function activates a
relay when the process value differs by more than the neutral zone from the setpoint. The two relays can be activated
independently by a common setpoint.
Output
2 relay outputs with a make contact connected to a common point.
Relay outputs can be installed in PELV/SELV circuits.

Documentation for routing diagram
The programming is menu-controlled. The main menus are numbered in level 0 (x.0), and the submenus are numbered in level
1 (x.1 to x.5). Each submenu has an accompanying entry menu. The menus are structured in such a way that the menus most
frequently used are closer to the default menu 0.0. Please note that programming is only possible when submenu 5.4 PAS has
the value 040.
Main, sub-, and entry menus are selected by the 3 function keys 3, 1and 2as
outlined in the routing diagram.
Activating 2in the submenus will display the current value of the entry and
parameter selection menus.
In entry menus, the digit that can be changed will flash.
Active digit position is shifted by the 3key, and the value is changed by the 1key.
When the decimal point flashes, its position can be changed by the 1key.
In entry menus with fixed parameters, you switch between the parameters by the 1
key.
Save by first activating 3and then 1simultaneously.
To return to the previous menu without changing the parameters, activate 2.
If a non-valid value is entered, the display will show Err for 2 s and then return to the
entry menu with the initial parameters.

Selection of function / description of functions
5.0 APP - Selection of function.
5.1 FUn - Selection of function.
Possible selections are:
001 = PID on/off controller:
The controller controls the time interval between the active relay outputs whereas the ON time of the relays is set
by the parameter Tp. When the process value is outside the proportional band, the UP / DOWN relay is permanently
activated. When the process value is within the proportional band, the UP / DOWN relay will be de-activated within a
variable interval depending on the distance from the setpoint. The neutral zone is the percentage On time (Tp%),
where no function is required on the output.
In a correctly tuned PID controller the constant error will be eliminated. This means that at a correctly tuned Xp, Ti,
Td, and Tp a regulation accuracy can be obtained close to what the process value can be measured to. It is therefore
important that the proportional band Xp, the integrating time Ti, the differentiating time Td, and the pulse time Tp
are tuned according to the individual process. Before setting the parameters, the method of regulation directly /
inverted must be determined. Direct controlling results in an active UP relay when the process value > the setpoint.
Inverted controlling results in an active DOWN relay when the process value > the setpoint.
Inexperienced users may use the following “rule-of-thumb” for determining the process parameters:
1. The pulse time Tp is set to a value so short that the process value is barely affected by the supplied energy.
2. Set Xp at max., Ti and Td to 0 (only proportional controlling).
3. Reduce Xp until the process starts oscillating.
4. Increase Xp twofold.
5. Set Ti at max.
6. Reduce Ti until the process starts oscillating again.

18 2286V102-UK
7. Increase Ti twofold.
8. If the controller is too slow reaching its setpoint, the differential controller can be activated. The differentiating
function augments the control signal proportionally to the rise time of the process signal. Therefore the setting
varies according to the process.
002 = PI step controller:
The controller controls motor-driven valves, throttle valves and dosage units via the UP / DOWN relays by a variable
OFF time according to the difference between the process value and setpoint and to the selected regulation
parameters. The variable parameters are: Xp - the proportional band, tAU - the exponential average time of the
active relay state - functions as integrating time, tP - the shortest active time of the relays, nEU - the neutral zone,
i.e. the band that the process is to be kept within, and HSt - the pulse width hysteresis within the neutral zone.
The PI step controller can be set as follows:
1. The setting method direct / inveted is determined. Direct controlling results in an active UP relay when the
process value > the setpoint. Inverted controlling results in an active DOWN relay when the process value > the
setpoint.
2. The minimum pulse width tP is set in s. A reasonable start value is 0.5% of the actuating time - the period from
closed to open state of the actuator.
3. The neutral zone nEU is set as the band which the controlling process is to be kept within. The neutral zone is set
in % of the input span.
4. The hysteresis HSt is set in % of the input span. A value of nEU/4 is a reasonable start value. In processes with
large dead times, HSt can with advantage be diminished.
5. Set the proportional band Xp (hP) to max. = 999% and tAU to max. = 999 s.
6. Reduce Xp (hP) until the process starts oscillating.
7. Increase Xp (hP) twofold.
8. Reduce tAU until the process starts oscillating.
9. Increase tAU twofold.
003 = 3-point controller:
The neutral zone, which is set in % of the input span, is placed symmetrically around the setpoint setting. When the
process input is lower than the neutral zone, the UP relay is activated until the process input increases to the
setpoint value. When the process input is higher than the neutral zone, the DOWN relay is activated until the process
input decreases to the setpoint value. The setting parameters are SEt setpoint, nEU neutral zone, dIr direct, and InU
inverted. Direct / inverted reverses the state of the UP / DOWN relays.
004 = dI/dt control:
The function monitors the size of the decrease or increase (dl) of the input within a set period of time (dt). A time
constant for the input value can be selected. The limit of the magnitude of the decrease / increase (dI) is entered in
the menus 1.2 and 1.3. The period of time (dt) over which the change is to be monitored is entered in the menus 1.6
and 1.7. At a positive (dI/dt), the relays will be activated when the change of the input signal exceeds the value (dI)
in menu 1.2 or 1.3 within the set period of time (dt) in menus 1.6 and 1.7. The relays will be de-activated when the
change is lower than the (dI) minus HS (the hysteresis) per (dt).
At a negative (dI/dt), the relays will be activated when the change of the input signal drops below the value (dI) in
menu 1.2 or 1.3 within the set period of time (dt) in menus 1.6 and 1.7. The relays will be de-activated when the
change is larger than the (dI) plus HS (the hysteresis) per (dt).
005 = Comparator with an external setpoint:
The process input A is compared with the external setpoint on input B. When the two signals are within the neutral
zone, no relays are active. When A is smaller than B minus ½ neutral zone, the DOWN relay changes its state. When A
is larger than B plus ½ neutral zone, the UP relay changes its state. The hysteresis is placed inside the neutral zone.
006 = Trip amplifier / window with an external setpoint:
Input A is connected to the process signal and input B is connected to an external setpoint.
The relay trip function can be selected as TF = Increment, decrement, or Window. If the trip function has been
selected as 1.1 = InC, the UP relay will be activated, when the input value (input A) is larger than the external
setpoint (input B).The relay will be de-activated again when the input value is smaller than the setpoint minus the
hysteresis. If the function 1.1 = dEC has been selected, the UP relay will be activated when the input value is
smaller than the setpoint. The relay will be de-activated again when the input value is larger than the setpoint plus
the hysteresis.
The neutral zone will offset the setpoint by the value entered in 1.3 nE1 and 1.4 nE2 - positive for increasing (TF =
InC), and negative for decreasing (TF = DEC) input value (input A). If you request the relays to be activated at
different input values, two different neutral zones must be entered.
The same description applies to DOWN relay.
The two trip relays use the same external setpoint (input B).

2286V102-UK 19
Window:
When the input signal is within the setpoint ± the neutral zone, the relay is inactive. The relay will be activated
when the input signal exceeds the setpoint ± the neutral zone.
When the input signal approaches the setpoint from a higher value, the relay will be de-activated at the setpoint
plus the neutral zone minus the hysterersis.
When the input signal approaches the setpoint from a lower value, the relay will be de-activated at the setpoint
minus the neutral zone plus the hysteresis.
This description applies to both UP and DOWN relay.
