4. THE DLM-080 RECORDER MEASUREMENT AND CONTROL
CHANNELS
The DLM-080 Recorder enables to define channel type for each of the channels as:
a) the PT-100 measurement channel (measurement range from -99.9 to +399.9° C, scale
interval 0.1 ° C)
b) the 0..20 mA measurement channel (measurement range from -99 to 999)
c) the 4..20 mA measurement channel (measurement range from -99 to 999)
d) a second-meter (range from 0 to 999)
e) a minute-meter (range from 0 to 999)
The DLM-080 FUTURE Digital Recorder – User’s Manual
26.11.2004
12
f) an hour-meter (range from 0 to 999)
g) multivibrator (second or minute or hour base)
4.1 THE PT-100 MEASUREMENT CHANNEL
In case if a measurement channel is defined as PT-100, readout values will be displayed in
a dynamic way, that is:
• within range from -99.9 to -10.0 with accuracy of 1 °C
• within range from -9.9 to +99.9 with accuracy of 0.1 °C
• within range from +100.0 to +399.9 with accuracy of 1 °C
4.2 THE 0..20 (4..20) mA MEASUREMENT CHANNEL
In case if a measurement channel is defined as 0..20 (4..20) mA, readout values will be
displayed according to the value of the F54-F61(SETUP) function.
that is:
• if F54-F61 = 3, then display range is 0.00 to 9.99 (0..20 mA)
• if F54-F61 = 4 , then display range is 00.0 to 99.9 (0..20 mA)
• if F54-F61 = 5 , then display range is 000 to 999 (0..20 mA)
• if F54-F61 = 6 , then display range is 0.00 to 9.99 (4..20 mA)
• if F54-F61 = 7 , then display range is 00.0 to 99.9 (4..20 mA)
• if F54-F61 = 8 , then display range is 000 to 999 (4..20 mA)
4.3 CHANNEL AS TIME-METER
In case if a measurement channel is defined as time-meter, then method of time metering
will be defined in the F38-F40 (SETUP) functions, that is:
• if F54-F61 = 11
, then second-meter
• if F54-F61 = 12
, then minute-meter
• if F54-F61 = 13
, then hour-meter
Moreover, it is necessary to define in the F62-F69 functions the method for time-meter
release, that is:
• F62-F69 = 0 time-meter reset, and it is released “manually” after pressing and
holding the
key (for proper channel) for approximately 2[s].
• F62-F69 = 1
then, if Tini contact closed, time-meter counts down until reaching
the set value, if time-meter reaches the set value and Tini contact opens, then the
The DLM-080 FUTURE Digital Recorder – User’s Manual
26.11.2004
13
time-meter will be reset to zero and as soon as Tini contact closes the count down
will be repeated, if the time-meter does not reach the set value and Tini contact
will open, time count down will stop and as soon as Tini contact closes the count
down will be further repeated
• F62-F69 = 2 then - if Tini contact closed, time-meter counts down until reaching
the set value – each opening of the Tini contact will result in resetting the timemeter to zero and as soon as Tini contact closes again, the count down will go on
ATTENTION: Reaction to change of Tini contact state takes approximately 3 seconds !
In order to connect Tini contact follow the procedure described on the DLM-080 back panel!
In order to ensure correct work of the channel as time-meter, the To(n) value
saved in the F14 – F21 cells and referring to work of the channel as a multivibrator
must be equal.
4.4 CHANNEL AS MULTIVIBRATOR
The DLM-080 enables to declare relay output as a multivibrator operating according to
the algorithm shown below.

•
τ - time in compliance with definition in the F14-F21 SETUP functions
Press and hold the key for approximately 3 sec. to reset time-meter and start the
time count-down process (diode built-in in the key is on). Press the key in order
to stop time count-down. Press the key to restart channel operation as a
multivibrator.

4.5 CONTROLLER RELAY OUTPUTS
As a standard the DLM-080 uses the algorithm of on-off controller with hysteresis. The
hysteresis value must be specified in the F14-F29 (SETUP) functions. Depending on
parameter setting in functions F30-F37 it is possible to define controller relay state as NR
(normally open, algorithm 1) or NZ (normally closed, algorithm 2).
Press the
key (for proper channel) in order to ensure that control for a given
channel is carried out according to setting of the set value – the diode is on. In case if a
diode built-in in the key (for proper channel) is off, then the control channel is
blocked and controller relay is open.

Press the keys (for proper channel) in order to set and modify already set
values for individual control channels. If any of these keys is pressed once, the set value
will be displayed, which is indicated by blinking of the displayed value. The display will
return automatically to read out value after approximately 2 seconds from the moment any
key was pressed last time.
5. HUMIDITY MEASUREMENT USING THE PSYCHROMETER METHOD
The Recorder permits humidity measurement using the psychrometer method. However,
in order to make it possible it is necessary to follow guidelines listed below:
1. if channel 1 is declared as humidity readout, (F54 = 1)
then “dry” temperature sensor is connected to channel no. 1
and “wet” temperature sensor is connected to channel no. 2
