43-TV-25-35 GLO Iss.4 Dec 06 UK 21A5E01001767-04Electrical InstallationAnalogue Output CardNot available on the SIREC D200 recorder.The Analogue Output card connections are made via 1 x 12-way screw terminal plug thatfits into a PCB header on the rear of the unit.The Analogue Output card position for the SIREC D300 is shown in Figure 2.3 onpage 14, and Figure 2.4 on page 15 for the SIREC D400.CAUTIONCONTROL UNIT DAMAGEDo not apply a hazardous live voltage between + and - pins within a channel (e.g. 60Vmaximum on voltage ranges, 5V maximum on millivolts ranges).The * pin should be connected only as part of ohms or R/T measurements. Ohms andR/T measurements share a common connection (* pin) with all channels in the samebank (the inputs are divided into two banks: inputs 1 to 3 are one bank, and inputs 4 to6, if fitted, are another bank). To avoid damage, ensure that a channel selected as ohmsor R/T remains floating, i.e. the sensor is not connected to any external voltage.Alternatively, if an ohms or R/T sensor must be biased to an external voltage, ensurethat the other two channels within the same input bank are floating or are biased to thesame voltage (i.e. - inputs of all three channels connected to the same voltage).Failure to comply with these instructions may result in product damageWARNINGHAZARDOUS VOLTAGESInsulation from channel to channel: Normally a channel can be safely connected to ahazardous voltage up to 300V AC common mode* with respect to earth. However,where a channel is connected to a safety low voltage circuit, an immediately adjacentchannel must be adequately insulated from hazardous voltages between 150V AC and300V AC max. This insulation should comprise of at least 1.5mm air gap, or a barrierrated greater than 1400V AC. This is to ensure that protection of the safety low voltagecircuit is fully maintained.*Common Mode voltage is a voltage applied between the whole channel and earth, notbetween pins on a channel. 300V AC is permitted at Measurement Category CAT ll(Overvoltage Category ll)Failure to comply with these instructions could result in death or serious injury. |
