How to dismantle system 2200
Picture 1:
The back panel of the module is detached from the housing by way of a
screwdriver.
Picture 2:
After this, the back panel can be pulled out together with the PCB, but
please notice the position of the PCB as there is a number of different
positions in the house. Do not pull the wires unnecessarily, instead pull the
PCB.
Switches and jumpers can now be moved.
When assembling the back plate and housing, please make sure no wires are
stuck.

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.
