T ype 99 5 The monitoring pilot should be upstream of the working monitor regulator . This enables a closer setpoint between the working regulator and the monitoring pilot. Special T ypes 161A YW and 627-109 monitoring pilots with quick-bleed operation have been designed to give faster response to abnormal downstream conditions.
