14. Alert outputs
The instrument offers in total four alert outputs which are accessible through a circular connector at
the bottom panel of the enclosure. Three of the outputs are paralleled with the green, yellow and
red signal lights. That means, if one of the signals is activated a 12V control voltage will be applied
the related pin of the connector. The voltage may be used for a second signal light or other alarm
devices. Make sure that the current drawn from this outputs will be not higher than 100mA each.
The fourth output (DOUT3) offers potential-free contacts (Opto-MOS relay, max. 24V/0.4A). The
output can be used as a measurement cycle-controlled switch to control external equipment.

15. User specific settings
The instrument is based on the DACM platform, which provides flexible tools for custom specific
configurations. Each of the functional blocks, the so-called components, can be configured and
controlled separately using the PC software dCONFIG. Changing the configuration requires caution
and should be carried out by skilled persons only (administrator). Erroneous settings may result in a
male function of the instrument. Before changing anything, the operator should read the recent
configuration from the unit and save it on PC as configuration file. If necessary, this file can be
written back to the unit in case of trouble. Each component offers a specific configuration window in
dCONFIG for all available configuration parameter. The dCONFIG software manual informs of the
procedures to access the various configuration windows.
15. 1. Changing the alert settings for radiometric measures
Configuration window of component SPEC1
It is possible to define two independent alert levels. The threshold values must be entered into the
edit fields "Alarm 1 threshold" and "Alarm 2 threshold". Several measures can be assigned to each of
the alert levels. These measures must be selected by marking the items within the list boxes "Alarm 1
source" and "Alarm 2 source". The threshold level is always related to the physical unit of the
selected measure. For example, one could use the first threshold for the dose value and the other
one for Radon and Thoron concentration. In delivery state the alert is routed to the red signal light
(switch output DOUT4). To disable the alert function, select the item "inactive" from the list.
