3.1.2.3 SOFT [ON/OFF] KEY
MFC-CB is equipped with a SOFT [ON/OFF] key and indicator LED on the bottom
left hand corner of the front panel. The purpose of the SOFT ON/OFF key is to put
MFC-CB into a dormant mode in which the display is turned OFF.
When MFC-CB is SOFT OFF, power is still supplied to DEV1 and DEV2 and the
MFC set points are maintained if the rear panel main power switch is on.
When MFC-CB is ON, the ON/OFF indicator is ON continuously. When MFC-CB is
SOFT OFF and the main power switch is on, the ON/OFF indicator blinks every
5 seconds.
When MFC-CB is SOFT OFF, receiving a remote command turns it ON.
3.1.2.4 ACTIVE DEVICE CHANNEL INDICATION
The MFC-CB active device channel (DEV1 or DEV2) is the channel whose set point
and measurement values are displayed on the top line of the MFC-CB display.
The characters on the bottom right hand corner of the display (
<D1> or <D2> )
indicate which channel is currently active. The active channel is the channel that is
affected by all channel specific settings and adjustments.
Channel specific MFC-CB settings include:
•
[K] (see Section 3.2.1).
•
[UNIT] (see Section 3.2.2).
•
[MFC] (see Section 3.2.6).
•
[SETUP] , <2jog> (see Section 3.3.2).
•
[SETUP] , <5adj> (see Section 3.3.5).
•
[SET MFC] (see Section 3.2.8).
Regardless of which channel is currently active from the display, both DEV1 and
DEV2 are always active in the sense that their set point is maintained.
3.1.2.5 DIRECT FUNCTION KEYS SUMMARY
Local operation of MFC-CB is through the front panel, 4 x 4, pressure
sensitive keypad. To minimize the use of multi-layered menu structures, the keypad
numerical keys also provide direct access to commonly used functions. The function
accessed is labeled on the bottom half of the each key. Direct function keys are
active whenever MFC-CB is in its MAIN run screen. Table 2 summarizes the
operation of the direct function keys. See the corresponding manual sections for full
detail on each direct function.
It may be useful to keep a copy of Table 2 near the MFC-CB, especially when first
becoming acquainted with its operation.
