Describe the switching duty
Give the switch tag, model, medium, range and unit. Identify the contact or output whose change matters to the operator. If the switch has two adjustable stages, list their duties separately; two settings do not necessarily share one acceptance limit.
As-found setting and adjustment
State whether the existing setting must be recorded before anyone changes it. Include the allowed trip and reset bands if your procedure defines them. For a vacuum switch, use the sign and reference convention on the instrument instead of converting values from memory.
Two pressures for one switch
A high-pressure switch may change contact state as pressure rises and reset at a lower pressure as it falls. The gap between those readings matters when the maintenance complaint is that the plant resets too early. Record the target trip and reset pressures separately, including units and the contact state the operator watches.
If the housing contains two independently set switches, label the terminals or channels in the request. A certificate row headed only with the instrument tag leaves the plant guessing which contact was checked when the unit goes back into service.
When the switch stays on the plant
At IMT Faridabad the utility supervisor and purchasing office may be at different gates. Give the supervisor's release window and ask RTS to agree on removal or site attendance before dispatch.
