Tm EI MILE ISLN O '@IT AG. 1 In Our review of recorts suo1ittea by licemees cancerniac 031 function of diesel unerators, we fina that to some cases the information availaule to tne control reau oper ator to indicat? the onerational stat'n of the liesel generatar aay be inprecise and could lead to nisintaroretation.
This can De caused by the sharinc of a sin'Tle annunciator statica by alarns tN: indicate conditions that rencier a diesel cenerator unable to respond to an automatic e'ergency start sinnal ane alarns that only indicate a war 71nq of aoncrmal, but not disablinq, conoitions.
Ano thnr cause can ne tne use of wording on an annunicitor windcri that does not specifically sa:,' that a diesel generater is iaoner:ble (i.e., unaaln it the time to rosneca to an t;tonatic e,erner cy start sipaal) @en in fact it is incpercale for that m:epose.
