1. INTRODUCTION
1.1 COMMON INTRODUCTION
1005RE is a new CE-approved series of controllers from Elmacron AB. In the series, there are
instruments for pH, Redox% and Redox mV measurement/ control.
1005RE is easy to program, calibrate and use.
The layout is clear; a large display with four LED-segments, diode indication for the menu and four
large function keys. All parameters are entered/changed with the function keys.
When connecting an electrode to 1005RE-ORP% the display shows the actual measured value in the
solution measured.
1005RE-ORP% is provided with an isolated output 0/4 - 20 mA, proportional to the measured value,
for connection to, for example, a computer, printer or other recording equipment. When measuring is
interrupted, the output stays frozen at the latest measured value.
1005RE has four relay outputs which can be set high/high, low/low, high/low and low/high. As
regulation form, you can make a choice between On/Off and proportional regulation.
Under the proportional regulation You have to choose between pulse and frequency related
regulation. The alarm delay can be set between 0 and 9999 seconds. The function "shutdown at
alarm" can be chosen on or off.
1.2 PARTS & ACCESSORY
1005RE is delivered without connection cables and electrodes.

4. REGULATION
4.1 ON/OFF REGULATION
At On/Off regulation the "on"-time is decided only by the limit value, when the limit is exceeded the
relay stays "on" until the measured value is within the limit values.
Example of On/Off regulation
Limit value 1 20%, high
Limit value 2 40%, high
4.2 FREQUENCY REGULATION
At frequency regulation the "on"-time is constant ( 100 ms ). The number of pulses /minute is decided
by the distance between the limit value and the actual value, the chosen proportional band and the
chosen max. frequency.
Example at frequency regulation.
Limit value 1 25%, high
Xp-band 20 %
Max frequency 100 pulses/min
The proportional band ( the XP-
band ) is given in % of full
measure range.
Measure range = 0 - 100%= 100
%-units, which gives Xp-band
20% of 100 %-units = 20 %-units
in our example.
The frequency ( pulses/minute ) is
given as a linear function between
25%and 45%, where the
frequency is 0 pulses/minute at
25%and 100 pulses/minute at
45%and above.

4.3 PWM ( pulse width modulated ) REGULATION
At pulse width modulated regulation the relay outputs "on"-time is decided by the distance between the
limit value and the actual value, the chosen proportional band and the chosen period time.
Example at pulse width modulated regulation.
Parameters:
Limit value 1 20%, high
Xp-band 25 %
Period time, T 100 seconds
The proportional band ( the XP-band ) is given in % of full measure range.
Measure range = 0 - 100 %= 100 %-units, which gives Xp-band 25% of 100 %-units = 25 %-units in
our example.
Relay "on" ( % of period time ) is
given as a linear function
between 20%and 45%, where
the "on"-time is 0% of the period
time at 20%and 100% of the
period time at 45%and above.

4.4 I-TIME
The integration time (I-time) can be set between 0 and 2000 seconds.
The set time starts when the measured value exceeds one of limit 3 or 4 (only when proportional
regulation is chosen). After expired I-time the frequency is doubled (at frequency regulation) or the on-
time is doubled (at PWM-regulation) compared with P-regulation. The doubling is performed with an
interval corresponding to the set I-time until either the measured value is within the limits or that max
frequency (alt. max on-time ) is reached. The regulation is then performed with max frequency (alt.
max on-time) until the measured value is within the limits.
In the example below the P-band is 80% (80 % -units), max frequency 180 Hz, I-time 600 seconds
and frequency regulation chosen as regulation form. The limit value is 20%.

5.3 CALIBRATION
The controller should be calibrated regularly, to reach a high security in the measurement. The
instrument is pre-set for calibration at 5%.
During the calibration, the latest output signal is "frozen", the relays are open and all regulation is
interrupted.
See appendix "Calibration instruction" for calibration.
5.4 OPERATION
Measuring is started when the power supply is turned on. After an interruption of the measuring, it can
be restarted by pressing =when the EXIT TO MEASURE diode is activated.
The display shows the actual measured value in the solution measured at the same time as the
corresponding mA-signal is sent to the output.
During the operation, the diode at MEASURE is activated. If a relay is closed the corresponding diode
activates.

6.2 PRE-CALIBRATION
The controller is always pre-calibrated when delivered. Pre-calibration is only necessary when the
instrument has been shut of for a longer period.
For safe and accurate pre-calibration it is recommended that the calibration is carried out by means of
the calibrator 1000CAL.
Connect the calibrator to the electrode input.
1. Turn the power off.
2. Connect the reference instrument to the electrode input.
3. Connect a mA-instrument to the mA output.
3. Press –and turn on the power supply. Keep the key pressed until the display shows
