nanodac RECORDER/CONTROLLER: USER GUIDE7 USER WIRINGUser wiring, created from the instrument front panel, allows parameters to be wired together so that, for example,a counter can be configured to be incremented when an alarm goes active. This can be used as analternative to iTools.This section is presented as two examples that show the general techniques used to create and delete wiresfrom the instrument user interface.Notes:1. These examples refer to Channel Configuration and to Virtual Channel configuration, descriptionsof which are to be found in sections 4.4 and 4.5 respectively.2. The destination parameter field has a small green triangle at the top left corner to indicate that ithas a wire routed to it.3A/3B (Relay)7.1 DRIVE RELAY EXAMPLETo drive the relay whose terminal contacts are 3A/3B, whilst the temperature being measured by Channel 2exceeds 30°C. For this example Channel 2 alarm 1 and a hysteresis of 4°C will be used.1. In channel 2, Alarm 1 page (see note), set the following parameters:Type: Abs.
