6.3.8 Step Down [
] and Step Up [] Keys
As shown in Figure 6.3A, the [
] and [] keys are located to the side (different for A and B Channels) of
the [Setpoint Value] key; one for Step Down [
], and another for Step Up []. Pressing an arrow key will
change the setpoint by the step value until the control limits of the channel are reached.
6.3.9 Control Pressure [Setpoint Value]
The number displayed inside the [Setpoint Value] key is the setting for a controlled pressure output.
When the [Control] key at the bottom of the active channel screen is switched to [On] the regulator will
attempt to present that precise pressure to the Measure/Control port on the rear panel. The setpoint
number is changed either by using the [
] and [] keys, or by touching the [Setpoint Value] key to input
a new number.
If the displayed number is beyond the range of a selected turndown in range hold mode, the number
will change to a control value within the limits of the turndown. The setpoint will change in value auto-
matically, but it will not be restored automatically if the previous turndown is reselected.
[Standby] key: When this key is ON all internal solenoid valves are closed.
[Measure] key: When this key is ON the active sensor and the Measure/Control port are connected
and isolated from the rest of the internal pneumatics.
[Control] key: When this key is ON the unit will attempt to control to the setpoint displayed.
[Vent] key: When this key is ON the internal pneumatics are open to atmosphere.
