Check

PERFORMANCE ORDER
1. To check the feeding tension, it is necessary to disconnect a block of switches (it is specified by an arrow).
2. To connect the voltmeter to average contact of a block and to "weight". To include ignition and to measure tension. It has to be 12 Century. If tension differs from specified, to check an electrical wiring.
3. For check of the switch of the modes of idling to connect an ohmmeter to contacts of "1" and "2" nests of a block. The ohmmeter has to show zero. It means that contacts are closed.
4. Then to turn a butterfly valve so that the switch was switched off. The ohmmeter has to show infinity. Otherwise it is necessary to adjust position of the switch. If it does not help, to replace the switch.
5. The switch of full opening of a butterfly valve is checked similarly, but an ohmmeter connect to contacts "2" and "3". It shows infinity. At turn of the gate against the stop the ohmmeter has to show zero.
6. It is possible to check conducting, having connected an ohmmeter to contacts "1" and "20", and then "3" and "26". In both cases the ohmmeter has to show zero. Otherwise in conducting there is a break.
