Page 2-14 V10/V7.5/V5/V3.5 Installation and Operation ManualIssue 3.5 Section 2 Preparation for Use and Installation2.2.16.3 High Reflected Power AlarmAn alarm output that indicates the peakreflected power is exceeding 276 W (V10),207 W (V7.5), 138 W (V5) or 103 W (V3.5) isavailable on TB1-10 (HIGH REFLDALARM).2.2.16.4 Changeover AlarmAn alarm output that indicates an automaticchangeover has occurred on the exciter,IPA, IPA PS or fan PS and the reserve(standby) module is enabled as the activeexciter, IPA, IPA PS or fan PS is availableon TB1-8 (CHGOV ALARM).NOTEIn V5/V3.5 transmitters, the exciter, IPA, IPAPS and fan PS have their own independentreserve (standby) options, which can becontrolled separately. The same is true forV10/V7.5 transmitters except that the IPAand IPA PS controls are ganged together(IPA A with IPA PS A and IPA B with IPA PSB).2.2.16.5 PA/Module Fail AlarmAn alarm output that indicates the RF outputis reduced because an RF power modulehas failed or has been turned off and is notcontributing to the RF output is available onTB1-9 (PA FAIL ALARM).2.2.16.6 Interlock Open AlarmAn alarm output that indicates the RF outputis inhibited because an external interlockswitch has been opened is available onTB1-5 (INTLK OPEN ALARM).2.2.16.7 IPA/RF Fail AlarmAn alarm output that indicates the RF outputis inhibited because of an exciter failure, IPAoutput low, or IPA VSWR condition isavailable on J6-3.2.2.16.8 High Temperature AlarmAn alarm output that indicates thetemperature of the intake air, exhaust air,reject load, PA or IPA exceeded theirmaximum temperature threshold is availableon TB1-11 (HIGH TEMP ALARM).2.2.16.9 Low RF AlarmAn alarm output that indicates the RF outputpower is less than a user configurablethreshold (default is 50%) is available onTB1-7 (LOW RF ALARM).2.2.17 Remote Status IndicationsOutputs that indicate the status of operatorcontrolled circuits are available on the remoteinterface PWB (A44) [see Figure 2-7a(V10/V7.5) or 2-7b (V5/V3.5) for pinassignment]. A switching device for eachoutput provides a current-sink-to-ground for alogic true status condition. Each circuit mustpresent impedance between the switchingdevice and a dc voltage source that limitscurrent to 50 mA. +15V is available at TB1-18of the remote interface PWB. If an external dcpower source is used, it must not exceed+24 V. Its return must be connected to aGND terminal [see Figure 2-7a (V10/ V7.5) or2-7b (V5/V3.5)] on the remote interface PWB.Unless otherwise noted, all remote interfacingis made to the remote interface PWB.2.2.17.1 Remote Control StatusA status output that indicates the local/remote control status of the transmitter isavailable on J4-22. A logic true condition ispresent when remote control is selected. Alogic false condition is present when localcontrol is selected.2.2.17.2 RF On StatusA status output that indicates the on/offstatus of the transmitter's RF power stage isavailable on TB1-14 (RF ON STATUS). Alogic true condition is present when the RFpower stage is enabled and ready toproduce RF output. A logic false condition ispresent when the RF power stage is turnedoff and will not produce RF output.2.2.17.3 Active Exciter StatusA status output that indicates which exciteris enabled as the active exciter is availableon TB1-15 (EXCTR STATUS). A logic truecondition is present when exciter 'B' isenabled as the active exciter. A logic falsecondition is present when exciter 'A' isenabled as the active exciter.
