Iekārta pēc 1. punkta, kas atšķiras ar to, ka signalizējošā elementā, kas satur: politronu, Šmita trigeri, impulsu ģeneratoru, RS-trigeri, &-elementu, skaitītāju, dešifratoru, koda pārveidotāju spriegumā, &-ventiļshēmas, kuru skaits atkarīgs no transformatora kontrolējamo elementu skaita, transformatora bojāto elementu transparentu un kopējo transparentu "nav normas", mērītājieejas pieslēgtas pie politrona vadplašu pirmās rindas, pielaižu ieejas pieslēgtas pie politrona vadplašu otrās rindas, kura darba kolektors pieslēgts pie Šmita trigera ieejas, kura izeja savienota ar kopējo transparentu "nav normas" un ar RS-trigera "0" iestādīšanas ieeju, kura "1" iestādīšanas ieeja kalpo par iekārtas palaišanas ieeju, bet izeja ir savienota ar &-elementa pirmo ieeju, kura otrā ieeja savienota ar impulsu ģeneratora izeju, bet &-elementa izeja savienota ar skaitītāja ieeju, kura izejas ir pieslēgtas pie koda pārveidotāja spriegumā un dešifratora ieejām, pie kam koda pārveidotāja spriegumā izejas ir pieslēgtas pie horizontāli novirzošajām platēm, bet dešifratora izejas pieslēgtas pie &-ventiļshēmu pirmajām ieejām, kuru otrās ieejas ir apvienotas un pieslēgtas pie Šmita trigera izejas, bet izejas ir pieslēgtas pie atbilstošajiem transformatora bojāto elementu transparentiem.
- 3. Iekārta pēc 1. punkta, kas atšķiras ar to, ka atslēdzošā elementā, kas satur politronu, Šmita trigeri, izvērses ģeneratoru, transparentu "avārija" un atslēdzošo releju, mērīšanas ieejas pieslēgtas pie politrona vadplašu pirmās rindas, pielaižu ieejas pieslēgtas pie politrona vadplašu otrās rindas, politrona darba kolektors ir pieslēgts pie Šmita trigera ieejas, kura izeja ir savienota ar transparentu "avārija" un ar atslēdzošā releja tinumu, bet izvērses ģeneratora ieejas pieslēgtas pie politrona horizontāli novirzošajām platēm.
