6. ALARMS

The DLM-080 Recorder enables setting of alarm thresholds in relation to set value. It is

required to preset the alarm threshold value in the F70-F77 (SETUP) functions. In order

to activate alarm press the

key in field of the channel, for which exceeded

threshold value is to be signalled. In case if value = 0 is set in the F70-F77 functions,

threshold exceeding control is off, and alarm is off no matter what is current state of the

key.

Blinking diodes in the keys (for proper channels) and intermittent signal on the

RE9 relay output indicate occurrence of an alarm.

Alarm enable unit, which is preset in SETUP (F70-F77 cells), depends on measurement

resolution !

E.g.: Channel 4 is defined as temperature measurement carried out with the Pt-100 sensor.

Measurement resolution (accuracy) is 0.1°C. Set value: 27 °C. In order to activate alarm

in the F73 cell value 5 has been entered. Then alarm will be activated as soon as read out

temperature value exceeds 27.5°C.

7. CO-OPERATION OF THE RECORDER WITH MASTER COMPUTER (RS-

485)

In order to connect the Recorder to master computer (RS-485) it is necessary to make

suitable connections between the Recorder and master computer according to Drawing

No. 1, and then to install the DLM-SIMPLE communication application. Each DLM-080

recorder connected to master computer with the RS-485 network shall have attributed its

own number in the RS-485 network (0-31). Specify this number in the F00 (SETUP)

In case, if there are two or more recorders in the network, which have the same

network number attributed, communication with these recorders will be impossible !
