These channels are intended to be connected to any of the RTD types incommon use. Specific hardware details are contained in Chapter 3.RTD input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels withthe settings shown here.The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,the relay will automatically generate configuration settings for every channel, based on the order code, in the same generalmanner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclu-sive, which is used as the channel number. The relay generates an actual value for each available input channel.Settings are automatically generated for every channel available in the specific relay as shown below for the first channel ofa type 5C transducer module installed in slot M.The function of the channel may be either “Enabled” or “Disabled.” If Disabled, there will not be an actual value created forthe channel. An alphanumeric “ID” is assigned to the channel; this ID will be included in the channel actual values. It is alsoused to reference the channel as the input parameter to features designed to measure this type of parameter. Selecting thetype of RTD connected to the channel configures the channel.Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements™ feature.In FlexElements™, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by settingthe operate level at 1.5 pu. FlexElement™ operands are available to FlexLogic™ for further interlocking or to operate anoutput contact directly.5.8.3 DCMA OUTPUTSPATH: SETTINGS ÖØ TRANSDUCER I/O ÖØ DCMA OUTPUTS Ö DCMA OUTPUT H1(W8) RTD INPUTS RTD INPUT H1↓↓MESSAGE RTD INPUT U8 RTD INPUT M5RTD INPUT M5FUNCTION: DisabledRange: Disabled, EnabledMESSAGE RTD INPUT M5 ID:RTD Ip 1Range: Up to 20 alphanumeric charactersMESSAGE RTD INPUT M5 TYPE:100Ω NickelRange: 100Ω Nickel, 10Ω Copper, 100Ω Platinum,120Ω Nickel DCMA OUTPUT H1DCMA OUTPUT H1SOURCE: OffRange: Off, any analog actual value parameterMESSAGE DCMA OUTPUT H1RANGE: –1 to 1 mARange: –1 to 1 mA, 0 to 1 mA, 4 to 20 mAMESSAGE DCMA OUTPUT H1MIN VAL: 0.000 puRange: –90.000 to 90.000 pu in steps of 0.001MESSAGE DCMA OUTPUT H1MAX VAL: 1.000 puRange: –90.000 to 90.000 pu in steps of 0.001
