If input of unit is overload by high-level signal, then output current is 3.5mA. If any error is detected (e.g. ICP error), then output current is 3.5mA. If current loop is switched-off by user (Loop max. value =0), then output current is 3.5mA. If blackout occurs or if unit is restarted, then output current is aprox. 1.3mA (even if current loop is in passive mode, see module connection). Output relay A3900-II unit contain output switch-over relay with one double throw contact (see Module connection). If ALARM value is exceeded, relay is switched on COM-1 contacts and 0-COM contacts are switched off (ALARM value has not to be zero). User can decide, which pair of contacts to use. Attention!!! From relay state cannot be find out the status of unit. If unit is not power supplied, then contacts COM- 1 are opened and contacts 0-COM are closed. If unit input is overloaded by signal from sensor (is signalized OVR on display), then relay remains in the previous state. If the status was not "ALARM" before the OVR, then the OVR does not cause switch of relay to "ALARM". Using of the relay is recommended, if the RMS value is measured. If the PEAK value is measured, any short-time high amplitude can generate alarm. Serial interface RS232 A3900-II is possible join to PC by standard crossing cable RS232 with connector CANNON 9 (female, female) and by reduction CANNON 9 / 10pin connector (see Module connection). This reduction is in the standard distribution shops. Data storage A3900-II is possible to connect to memory module 3600MEM. There are stored measured data to standard compact flash card. Stored data can by analysed in PC. For further information contact the ADASH Ltd.
