7.2. Connection.
7.2.1. Plug in the temperature probe to the 5 pin DIN socket. Place the temperature
probe into the sample ensuring that at least 40mm of the probe tip is in contact
with the sample. Ensure the temperature probe is correctly plugged into the 5-
pin DIN socket at the rear of the MC810B Controller.
Note: Should the temperature probe become disconnected or fail open circuit,
the display will indicate “or” and a dot next to the alarm symbol will illuminate.
7.2.2. Connect the IEC output plug to your heating apparatus as illustrated.
or
7.2.3. Connect to the mains electricity supply. Turn on using the On / Off Power
switch. The amber neon will illuminate when power is being supplied to the
output. Depending on the operating mode, the amber neon may be on
continuously, or switch on and off.
7.3. Control Modes Explained.
7.3.1. Basic On / Off Controller.
The On / Off controller output has only two states. Fully on and fully off. Fully
on is when the temperature is anywhere below set point, and fully off, when
the temperature is anywhere above the desired set point.
7.3.2. On-Off Controller plus Hysteresis.
To prevent detrimental control chattering as the temperature crosses the set
point, an On / Off differential or ‘hysteresis’ can be added to the controller
function.
When a hysteresis value is entered (for example, say 3°C), the controller will
switch off once the set point temperature has been reached and will not
switch back on again until the measured temperature falls 3°C below the set
point.
For example, in a heating application, with a 150°C set point and a 3°C
hysteresis value entered, the controller will switch off at 150°C (there may be
some overshoot) and will not come back on again until the temperature falls
to 147°C.
The hysteresis figure should be set to give improved control of temperature
without excessive chatter. The amount of hysteresis determines the minimum
temperature variation possible, although process characteristics will add to
this differential.
On / Off functions are only accurate when the heating mass is relatively large,
and the heater will cause overshoot and wide variations in temperature.

Page 12 of 24 M6493 Issue 10.3
7.3.3. Proportional, Integral and Derivative Control.
A proportional controller continuously adjusts the power, so the heat input to
the process is approximately in balance with the process heat requirements
in order to maintain a stable temperature. The range of temperature over
which power is adjusted is from 0% to 100%. This temperature range is
called the ‘Proportional Band’. The proportional band is adjustable for
differing process conditions (zero proportional band returns the controller to
basic on / off control).
The temperature difference between the stabilised temperature and the set
point is called the ‘Offset’. The offset can be reduced by adjusting the integral
term of the PID controller. This is achieved using the integrative action time
and integrative action reset.
A derivative function can be combined with the proportional controller to
provide the controller with the ability to shift the proportional band either up to
or down to compensate for rapidly changing temperature (i.e. when an oven
door is opened or cooler fluid is introduced into a controlled vessel). The
derivative function increases the controller gain during temperature changes,
and can help to reduce overshoot on start-up.
Hence, a three-mode PID controller combines the proportional, integral and
derivative actions, to allow the set point temperature to be approached
relatively smoothly with minimal overshoot.
7.4. Front Panel Controls
The MC810B controller has four front panel keys as described below.
7.4.1. The key is used to increase the value of the parameter shown on
the display or to scroll through the parameter menu.
7.4.2. The key is used to decrease the value of the parameter shown on
the display or to scroll through the parameter menu.
7.4.3. The key is a dual function key. It is used to display and store the
value of the selected parameter when in ‘Programming’ mode. When used with
the it is used to display the ‘Setpoint’ value.
7.4.4. The is an ‘Exit / Stand-by button. Press of 3 seconds to turn unit on
or off.
7.5. Operating Modes.
7.5.1. The MB810B has two modes of operation: Function mode and Programming
mode. The unit enters Function mode immediately following power up in auto
test phase. In Function mode the display shows the temperature measured by
the temperature sensing probe. The output power will also be switched on or off
as appropriate. If the output power is on, the amber neon indicator on the front
panel will be illuminated. The only parameter which can be altered in the
function mode is the set-point. See 7.7.1
7.5.2. In Programming mode, all the other parameters apart from set-point can be
altered. To gain access to the programming mode from Function mode, press
the keys
and . Keep them pressed for five seconds. The
output power is always off when in programming mode. If approximately 25
seconds elapse while in programming mode with out a key being pressed the

Page 13 of 24 M6493 Issue 10.3
MC810B controller will activate with the last preset parameters. Furthermore by
pressing the key from any condition the unit will revert back to
Function mode.
7.6. Configuration.
7.6.1. Enter Programming mode as described in paragraph 7.11 The available
parameters in the configuration menu are as shown in the table on pages 15 to
17.
7.6.2. Only channel 1 / output 1 is active on the MC810B controller. Other available
parameters are disabled through the factory default settings.
Please Note:- Should any of the parameters become altered accidentally, they may
be restored to their factory settings by programming the values shown on page 18.
7.7. Entering the Set point. (Channel 1 only).
7.7.1. Press and release button . Observe the display shows 1SP and the
LED L1 blinks and then the associated value.
Press the and to set the desired value (adjustment is within
the minimum SPL and maximum SPH limit).
To store the new value press button or wait 10 seconds.
To return to operational mode without saving the settings press the
Exit / standby button.
7.8. Stand-By
7.8.1. Press the button and wait for the 3 seconds. The word ‘OFF’ will be
displayed. To resume press the button once again for another 3
seconds and the display will return to normal operation.
7.9. Keypad Lock.
7.9.1. The keypad lock avoids undesired and potentially dangerous operation,
which might be attempted while the controller is in operation. In the INFO menu,
set the parameter to LOC=Yes to inhibit all of the function buttons. To resume
normal operation of the keypad, adjust the parameter setting to LOC=No. This
is accessed by pressing the and immediately releasing it.
7.10. Controller Auto-tuning in PID mode.
Before commencing.
7.10.1. In the setup mode (see configuration 7.6) set 1CM=PID; make sure that 1CH
matches the desired operation mode (1CH=REF for refrigeration control,
1CH=HEA for heating control); then adjust set-point 1SP at the desired value.

Page 14 of 24 M6493 Issue 10.3
Start Auto-tuning.
7.10.2. During normal operation, keep buttons and pressed for
3 seconds.1CT blinks on the display. With + or
pressed set the cycle time in order to define the dynamic process to be
controlled. To abort the auto-tuning function, press ; to start auto-
tuning press + or wait or 30 seconds.
During Auto-tuning.
During the entire auto-tuning phase, the display alternates TUN with the actual
temperature being measured. In case of power failure, when power is restore,
after the initial auto-test phase, the controller resumes the auto-tune function.
To abort the auto-tuning, without modifying the previous control parameters,
keep button pressed for 3 seconds. After auto-tuning has successfully
taken place the controller updates the control parameters and starts to control.
Errors
If the auto-tuning function failed, the display shows an error code:
•E1 time out 1 error: the controller could not bring the temperature within the
proportional band. Increase 1SP the case of the heating control, vice versa,
decrease 1SP in the case of refrigeration control and re-start the process.
•E2 timeout2 error: the auto-tuning has not ended within the maximum time
allowed (1000 cycles). Re-start the auto-tuning process and set a longer
cycle time 1CT.
•E3 temperature over-range: check the error was not caused by a probe
malfunction, then decrease 1SP in the case of heating control or increase
1SP in the case of refrigeration control and then restart the process.
•To eliminate the error indication and return to the normal mode, press the
button .
Control improvement.
•To reduce overshoot, reduce the integral reaction reset 1AR
•To increase the response speed of the system, reduce the proportional band
1PB. Caution: doing this can make the system less stable.
•To reduce swings in steady-state temperature, increase the integral action
time1IT; system stability is thus increased, although it’s response speed is
decreased.
•To increase the speed of the response to the variations in temperature,
increase the derivative action time1DT. Caution: a high value makes the
system sensitive to small variations and it may be a source of instability.

Proportional bandwidth.
Temperature control takes place by changing the
ON time o the output: the closer the temperature to
the set-point, t he less time to activate. A small
proportional band increases the promptness of the
response of the system to temperature variations,
but tends to make it less stable. A purely
proportional control stabilises the temperature
within the proportional band but does not cancel
the deviation from the set-point.
With 1PB=0 the output is always off.

Page 16 of 24 M6493 Issue 10.3
1IT
0..999s
Integral action time.
The steady-state error is cancelled by inserting an
integral action. The integral action time, determines
the speed with which the steady-state temperature
is achieved, but a high speed (1IT low) may be the
cause of the overshoot and instability in the
response. With 1IT=0 the integral control is
disabled
1DT
0…999s
Derivative action time
Response overshoot may be reduced by inserting
a derivative Action. A high derivative action (1DT
high) makes the system very sensitive to small
temperature variations and causes instability. With
1DT=0 the derivative control is disabled.
1AR

Decreasing the paramater 1AR reduces the integral ontrol action zone, and consequently the
overshoot (see figure on paragraph 1IT).

Cycle time.
It’s the period in which the output ON time changes. The quicker the system to be controlled
reacts to temperature variations, the smaller the cycle time must be, in order to obtain higher
