1. APPLICATION
RT1800 is a compact, multifunctional all-purpose microprocessor controller. Its user-configurable analog input
allows on-site adaptation to various thermocouple and RTD sensors as well as current and voltage output
transducers for pressure, relative humidity, flow, etc. The RT1800 controller may be ordered with a second
analog input for cascaded operation or remote set-point setting.
A set-point profile control is an additional option.
The device may be equipped with up to 4 relay and/or analog outputs that may serve as control outputs,
limit comparators, alarm outputs, etc. The built-in timer may be programmed to fully control one of the output
relays providing convenient delay at start-up.
The controller offers all standard PID features including bumpless auto/manual changeover. The two displays
─one for the process variable and another for the set point ─plus the control-action bar-graph allow all
necessary information to be read at a glance.
The optional digital interface, either RS232 or RS485, provides connection to an operator station driven
network as well as hierarchical control.
The switch-mode power supply provides for trouble-free operation under heavy mains voltage variations
(from 85 to 265 VAC).
The unit is specially designed to sustain the heavy electromagnetic disturbances that often arouse
in industrial environment by the means of optical decoupling of all inputs and outputs and special noise
suppression circuits.

3. OPERATION
3.1. General programming sequence
Controller parameters are grouped in 4 levels (parameter groups) according to their frequency of use.
The following order of parameter programming is recommended:
1. Enter level 2 and set the parameter LCK= 1111 to get access to level 4.
2. Enter level 4 to configure basic controller settings (input and output number and use, which
parameters of the other levels will be available for adjustment and which will be hidden ...).
3. Switch back to level 2 and set the parameter LCK= 0000 to get access to level 3.
4. Enter level 3 and set its parameters (input type, alarm type, output action direction ...).
5. Enter level 2 and set preliminary values for the PID (ON/OFF) parameters (proportional gain,
hysteresis …).
6. Enter level 1 and adjust the set point, alarm limits, etc.
7. When the controller is already mounted in place and the system starts functioning, readjust
PID (ON/OFF) control parameters to achieve satisfactory system performance.
8. Switch over to level 2 and set the parameter LCK= 0001 or 0101 to prevent unauthorized
personnel from changing vital controller parameters (level access locking).
3.2. Switching among parameter levels
Normally, the controller operates at level 1 and shows the set-point value on its lower display
and the measured value ─on the upper display.
Switching over to level 1 may be done in either of the following ways:
•Automatically, when no key has been pressed for 1 minute, regardless of the level.
•By using the A/M key, regardless of the level.
•Automatically, after power-on. At start-up, the input type and range appear consecutively on the display,
followed by the measured value and the set point from level 1.
•Automatically, after exiting level 2, 3, or 4.
Entering level 2:
•While the device operates at level 1, press and hold SET for 5 seconds.
Exiting level 2 may be done in either of the following ways:
•By holding SET depressed for 5 seconds.
•By pressing A/M. Mind that this also toggles between AUTO and MANUAL modes. Does not function
while parameter value is being adjusted (finish parameter adjustment first by pressing SET).
To get access to level 3, set LCK= 0000 from level 2 beforehand.
To get access to level 4, set LCK= 1111 from level 2 beforehand.
Switching over to level 3 or 4:
•While the device operates at level 1 or 2, press and hold SET and Wfor 5 seconds.
Exiting level 3 or 4 may be done in either of the following ways:
•By holding SET and Wdepressed for 5 seconds.
•By pressing A/M. Mind that this also toggles between AUTO and MANUAL modes. Does not function
while parameter value is being adjusted (finish parameter adjustment first by pressing SET).
If, after parameter adjustment at level 4, the device expects readjustment at levels 2 and 3, the value
of the parameter LCKautomatically changes to 0000.
3.3. Parameter adjustment
•Display the parameter symbol on the upper (red) display and the current value on the lower (green) display.
•Press Wto enter parameter value adjustment mode. The rightmost digit starts blinking. To select
another digit, use W. To increase or decrease the blinking digit value, use respectively Sor T.

•Press SET to confirm the adjusted value and exit parameter value adjustment mode.
•To display the next parameter in the row, press SET.
3.4. Controller programming
Automatic PID control parameter tuning (Auto-tune)
Before starting the Auto-tune function, ensure the controller is properly installed, the system is functional,
and the main parameters from levels 3 and 4 are already adjusted. The auto-tuning function automatically sets
the values of the following parameters: P1, i1, db1, GAP1, P2, i2, d2. The operator must set
manually the duration of the on/off output relay cycle CYt1, CYt2. For current output ─set to 0, for relay
output ─try with 10.
a) Set the parameter At to YES.
b) Set a temporary automatic decrease of the set point during auto tuning via the AtVLparameter.
With AtVL = 0, the tuning process will be performed around the set point. With AtVL = 5°C
and set point SV = 200 °C, the auto-tuning will be performed around 195 °C (this avoids overheating
due to the process variable cycling during the auto-tuning process). If in doubt, set AtVL = 0.
c) Unsuccessful auto-tuning. Possible reasons are:
•Too high AtVL value (if in doubt, set to 0).
•Great system inertia. Set PID parameters manually.

Level access control (parameter LCK)
LCK =0100 - levels 1 and 2 are accessible, and their parameters may be adjusted;
LCK =0110 - levels 1 and 2 are accessible, but only the parameters from level 1 may be adjusted;
LCK =0001 - levels 1 and 2 are accessible, but their parameters (except for set point) may not
be
adjusted;
LCK =0101 - only level access control parameter may be adjusted.
The level access control parameter may always be adjusted.
LCK =0000 allows access to level 3 (from level 2, press and hold SET иWfor 5 s)
LCK =1111 allows access to level 4 (from level 2, press and hold SET иWfor 5 s)
Proportional band (parameters P1 and P2)
The relation between the proportional band P and the proportional gain KPis as follows:
KP= 10 000 / ( P * INPUT_RANGE ),
KP[%/°C] is the proportional gain, P[%] is the proportional band,
INPUT_RANGE [°C] is the input range high limit (e.g. with input range -200...400 °C,
INPUT_RANGE = 400)

* "suppression" means that after power-on, alarm action is suppressed until the alarm situation normalizes
at least for a moment. In this way, alarm activation is avoided while the system is reaching steady state.
Detailed alarm function diagrams are given on the next page.

4.4. Linear input adjustment
When the device input is programmed as analog linear input, the correspondence between input voltage (current)
and displayed value may be specified. For instance, the correspondence may be from 10 mV input →0 oC
to 50 mV input →1000 oC. For this purpose, the following parameters are used: AnL1,AnH1, and dP.
The displayed range defined by AnL1, AnH1 should be within the allowed input range defined
by parameters LSPL and USPL. Sometimes the allowed input range needs to be extended first.
•Connect a calibrator to the controller analog input.
•From level 4, grant access to parameters AnL1,AnH1, and dP by setting SEt2 = ХХ1Х.
•Enter level 3 and select the desired range of the analog input by setting inP1 = AnX (see Appendix 4.1).
•Set the calibrator to generate a signal (voltage or current) corresponding to the lower end of the input range.
•From level 3, enter parameter value adjustment mode for AnL1 for the displayed value at the lower
end of the input range. Values appear on both displays. The value on the upper display is the measured
value that the device would display with the current input value. To make the adjustment, increase or
decrease the value on the lower display until the upper display shows the desired measured value to be
displayed in normal operation at lower input range.
•Set the calibrator to generate a signal (voltage or current) corresponding to the higher end of the input range.
•From level 3, enter parameter value adjustment mode for AnH1 for the displayed value at the higher
end of the input range. Values appear on both displays. Increase or decrease the value on the lower
display until the upper display shows the desired measured value to be displayed in normal operation
at higher input range.
•Repeat the last four steps until satisfactory correspondence is achieved at both input range ends.
•If necessary, from level 3, adjust the position of the display decimal point via dP.
4.5. Analog output adjustment
When the device has a linear output, it is factory tuned by default. If readjustment is necessary, follow this
procedure:
•For easier adjustment, switch to manual mode by pressing the А/Мkey (The MAN LED should light up).
•Connect a mA-meter to the controller analog output.
•From level 4, grant access to parameters CL01 and CH01 by setting SEt4 = 1ХХХ.
•From level 2, set to the parameter P1 a value other than zero. Set also CYt1 = 0.
•From level 1, set 0UtL = 0(minimum output value). At this moment, if factory setting is correct,
the output current should be 4 mA.
•If adjustment of the output setting is needed, from level 3, change the value of parameter CL01
for low control range limit. Increased / decreased the value, until the miliammeter reads 4 mA.
Try with CL01 = 0192.
ATTENTION: At an attempt to achieve currents lower than 2-3 mA, considerable nonlinearity appears,
since the device is designed for output 4...20 mA, and not for 0...20 mA.
•Set 0UtL = 100. At this moment, if factory setting is correct, the output current should be 20 mA.
•If adjustment is needed, from level 3, change the value of parameter CH01 for high control range
limit. Increased / decreased the value, until the miliammeter reads 20 mA.
Try with CH01 = 3096.
•Repeat the last four steps until satisfactory correspondence is achieved at both range ends.
Note: In the case of such configuration ─first control output - analog, second control output - relay type ─
for better operation of the analog output, is advisable to disable the relay control output by setting,
from level 4, 0UtY = 0.

4.6. RAMP-SOAK adjustment
The Ramp-Soak function is available ONLY for models with standard PID-Fuzzy algorithm (not with pattern
set point)! To program the RAMP function, follow the procedure below:
•From level 4, set SEt2 = ХХХ1to enable AL3 access
•From level 4, set SEt4 = ХХХ1to access ALd3
•From level 3, set ALd3 = 9to enable RAMP function - it will replace AL3 by rAMP
•From level 1, adjust the rAMP slope from 00.00 to 99.99 [°C/min]
To program the SOAK function, follow the procedure below:
•From level 3, set ALd1 (ALd2)= 19 to use SOAK timer function
•From level 1, adjust the AL1 (AL2)Soak time from 00.00 to 99.59 [h.min]
The following example illustrates RAMP-SOAK function:
•Let SV = 100 °C, rAMP = 10.00 °C/min, AL1 = 00.10 min, PV = 25 °C
4.7. Profile (pattern) control programming
The profile control with is available ONLY for models with PID-Fuzzy algorithm with pattern set point!
To program the profile control, follow the procedure below:
•From level 4, set SEt8 to adjust profile program repeat, start and power failure options
•From level 4, set SEt9 to adjust time units
•From level 3, set SEtA to adjust profile program run or end alarm
•From level 3, set WAit to adjust WAIT option
•Set the alarm type "07" and alarm functions as described in 4.2
•From level 1 follow the steps below to create a pattern, consisting of RAMP and SOAK segments
(up to 2 patterns with 8 segments or 1 pattern with 16 segments can be created)
Note: If you want the program to stop before the 8th or 16th segment just set the last segment OUtto '0'.
4.7.1. Keyboard operating commands
•Program starts by pressing S. PRO front panel LED starts to blink
•Program holds by pressing T(pause). PRO stops blinking but lights
•To jump to previous segment press S+SET
•To continue a stopped program at segment end (WAit message) press S+SET
•Program stops (RESET) by pressing T+SET. PRO front panel LED will be off.
