V10/V7.5/V5/V3.5 Installation and Operation Manual Page 3-19Section 3 Operating Instructions Issue 3.5Table 3-7: Power Module Interface PWB - Controls and IndicatorsPANELMARKING DESCRIPTIONPA FAIL 1 – 4DS1 – DS4When turned on (red), indicates:- the associated IPA or RF power module’s PA (1 through 4) and/or itsassociated circuitry has failed, or- the non-operational PA (PA FAIL 3 or 4) in dual PA IPA modules(NAA54A/03 and NAA55A/03, used only in V5 and V3.5 transmitters)NOTE: PA FAIL 1 (DS1) and PA FAIL 2 (DS2) LEDs are not installedon PWBs contained in dual PA IPA modules.PA VOLTSDS5When turned on (amber), indicates the PA voltage is present and beingapplied to the associated RF power module.BIAS/DUAL IPAE1Bi-position selection jumper that can be used to configure an RF powermodule for use as an IPA module in dual PA IPA V5/V3.5 transmittersonly.This jumper is factory set in the BIAS position (shorting pins 1 and 2)and requires no adjustment in a V10/V7.5 transmitter.The jumper is factory set in the DUAL IPA position (shorting pins 2 and3) for a dual PA IPA module in a V5/V3.5 transmitter.If an RF power module is being used as a dual PA IPA module in aV5/V3.5 transmitter (as described in 5.11.2), the jumper should be set toDUAL IPA (shorting pins 2 and 3).Table 3-8: Miscellaneous Controls and IndicatorsPANELMARKING DESCRIPTIONDS1 – DS3 When turned on (amber), indicates that ac voltage is being applied tothe ac distribution assembly (A1), therefore ac voltage is present in thetransmitter cabinet. For 3-phase ac power source configurations, thereis an LED for each phase. For 1-phase ac power source configurations,all three LEDs are connected between the ac lines (or line-neutral).
