Fast Keys
On the Rosemount 3102, RL2 is factory-set to be a fault relay. In this mode, it de-energizes under
Lost Echo (LE) or fault conditions. The relay de-energizes if the power fails.
The RL2 mode of may be changed to control mode by selecting "Setpoint" and then entering
RL2 PV On Point (P074) and RL2 PV Off Point (P075) values. All relay set-point values must be
entered in the PV units.
The on point value may be greater or smaller than the off point value.
Note
The relay RL2 is switched off by selecting "Setpoint" and then setting the On and Off points to
an identical process value.
