Tērā pea ko tētahi o ngā taputapu tāpiri tino noa i roto i te aunoatanga o te whakahaere tukanga he pūmana whakaatu atamai. Ko te mahi a te whakaaturanga, e ai ki te whakaaro, he whakarato i ngā pānui e kitea ana mō ngā tohu e puta mai ana i tētahi taputapu matua (te paerewa 4~20mA anaro mai i tētahi tuku, me ētahi atu) mō ngā kaimahi kei te papaanga. I roto i te mahi, he maha ngā tuku, ngā pūoko rānei e whakamahia ana kāore i whirihorahia ki tētahi whakaaturanga matihiko, ko te tikanga kāore he tohu pānui ā-rohe, ā, ka tukuna noa ngā putanga ki tētahi atu taputapu mā roto i ngā waea hiko.
Tērā pea ka whai wāhi te kaiwhakahaere whakaaturanga e mau ana i te papa i roto i ēnei āhuatanga ina hiahiatia he tohu tāpiri mō ngā kaiwhakahaere mara. Hei tauira, he momo whakauru kore-whakaaturangatuku taumata rukuka taea te whakairi mai i te tihi o tētahi oko rokiroki teiteikua honoa ki tētahi pūmana whakaatu i runga i te whenua hei whakaatu i te pānui taumata i te wā tūturu.
Haunga te whakamahinga o te arotau i ngā wāhi whakahaere o nāianei, tera pea ka pātai te tangata he aha e kore ai e hiahiatia he whakaaturanga ā-rohe e piri ana ina tono ana i ngā taputapu matua hou, kaua e hoko taputapu tohu tāpiri? He maha ngā painga o te kaiwhakahaere ki te whakataurite ki te whakaaturanga a te tuku:
★Ngāwari. Ka taea te whakairi noa i te pūmana whakaatu ki te wāhi e hiahiatia ana, ā, ka taea te whiwhi me te whakaatu i ngā putanga mai i te tuku i te rohe mōrearea, i te wāhi uaua rānei.
★Hototahi. He maha ngā kōwhiringa rahi o te pūmana whakaatu, ā, he whānui, he taea hoki te whirihora i te tohu tāuru me te tohu tāputa.
★Ngā āhuatanga tāpiri. Tērā pea he mahi anō tā te tohu atamai, pērā i te putanga whāngai 24VDC me ngā whakawhiti ara-4 mō te whakahaere whakaoho.
Hei kaihanga taputapu, ka taea e WangYuan te whakarato i ngā raupapa oNgā Tohu Ahumahi Maamaate whakatutuki i ngā hiahia o ngā kiritaki mō ngā taputapu tuarua.
