INSTRUCTIONS FOR ASCON ELECTRONIC TEM-
PERATURE CONTROLLER M
ODEL
MS 30/099 FOR
HEAVY OIL IN BURNER PREHEATER(S)
The “MS 30” electronic controller cab be used in various ways and
must be correctly programmed (configured) as a function of the use
that is to be made of it. Use and configuration will depend on the
number of electric preheaters on the burner.
!
When supplied to us by the manufacturer ASCON, the new
controller has not been configured (configuration 9999) and is
therefore not able to perform the function required. Likewise,
when the controller is ordered from us as a “replacement”
or “spare”, it is not capable of performing the function in
question.
The “MS 30” electronic regulator uses two output circuits,
Y1 and Y2.
Circuit Y1 controls 1 or 2 preheaters using proportional,
integral, derivative (PID) regulation.
Circuit Y2 controls 1 or 2 preheaters with ON – OFF regu-
lation.
Using the “MS 30” regulator with just one electric preheater
The regulator uses contact Y1 (proportional, integral, derivative
regulation known as PID regulation) as a regulation thermostat to
control the preheater elements, while contact Y2 (ON-OFF regula-
tion) is used as a minimum thermostat.
Configuration for one electric preheater
C = 1 D = 0 E = 4 F = 5
Indicative parameters
SP = 130.0 °C t.d. = 0.8 minutes S.P.L.1 = 100 °C
SP.2 = 110.0 °C t.c. = 10 seconds S.P.L.h. = 250 °C
P.b. = 6 % Yh = 100% SLOP = 0
t.i. = 4 minutes Hy.2 = 1%
To all intents and purposes, this configuration is suitable for most
users, but we cannot exclude the possibility of changes being
necessary in certain cases.
Using the “MS 30” regulator with two or more electric pre-
heaters
It should be noted that the two or more preheaters constitute two
or more resistor arrays.
One array is controlled by circuit Y1 of the controller (PID control
= Proportional, Integral, Derivative). The other array is controlled
by circuit Y2 of the controller (ON - OFF control).The two or more
preheaters are hydraulically connected in series. The preheater
that the fuel first enters must be controlled by circuit Y2 (ON -
OFF control, approximately 110 °C). The fuel leaves the first pre -
heater heated to 110 °C and enters the second that is controlled
by circuit Y1 (PID control, approximately 130 °C). In the second
preheater, the temperature of the fuel is increased to 130 °C.
Configuration for two or more electric preheaters
C = 1 D = 0 E = 4 F = 6
Indicative parameters
SP = 130.0 °C t.d. = 0.8 minutes S.P.L.1 = 100 °C
SP.2 = 110.0 °C t.c. = 10 seconds S.P.L.h. = 250 °C
P.b. = 6 % Yh = 100% SLOP = 0
t.i. = 4 minutes Hy.2 = 1%
To all intents and purposes, this configuration is suitable for most
users, but we cannot exclude the possibility of changes being
necessary in certain cases.
CONFIGURATION
This operation enables setting of controller functions C - D - E - F
in accordance with required use; The number specified in the table
above is set for each function.
C = 1 = Use of probe PT 100 (temperature can be set within the
range - 100 to + 300 °C).
D = 0 = Use of relay output Y1 (3A - 250V), terminals 13 - 14.
E = 4 = “Reverse” control of circuit Y1 , contact closed with probe
“cold” and open with probe “hot”. PID control ( P roportional,
I ntegral, D erivative). Safety = 0% = in case of failure of probe
PT 100 , contact Y1 opens and therefore cuts off power supply
to the load (contactor and thyristor that controls the resistors).
F = 5 = ON-OFF control (independent of Y1 ) for circuit Y2 , termi-
nals 11 - 12. Contact closed with probe “hot” (active high) and
therefore contact open with probe “cold”.
F = 6 = ON - OFF control (independent from Y1 ) for circuit Y2 ,
terminals 11 - 12. Contact closed with probe “cold” (active low)
and contact open with probe “hot”.
HOW TO USE THE KEYS:
F
Press once to move to the next function. Press repeatedly to
return to the previous function.
► Press once to enable changes starting with the last figure on
the right that begins to flash. Press again to confirm and enter
the flashing figure.
◄ Press in order to move to the figure on the left that
begins to flash and at the same confirm (enter) the
flashing figure.
◄ Press to alter the flashing figure.
!
WARNING: The time available after pressing a key is 10
seconds. After10 seconds have passed, the display returns
to its initial position.
In order to proceed with configuration, the controller must be fitted
to the switchboard and connected to both probe PT 100 and the
power supply (230V).
The display lights up (numbers and/or letters). Press F key repe-
atedly until obtaining the wording ConF . Press key twice and the
wording PASS will appear (at the bottom) and 9999 (at the top) with
the last 9 on the right flashing.
It is necessary to enter the PASS word (access password = 3333 ).
