To select outputs 3 and 4 as events, enter the Setup menu by pressing
the Up/Down keys simultaneously for 3 seconds. The SEt parameter
appears in the lower display. Press the Up or Down key until OtPt is
shown in the upper display. Press the Mode key until you reach the Ot3
parameter. The default for Ot3 is AL3 (alarm 3). Change the value to
Ent3 (event 3) if it hasn’t already been done. Press the Mode key to con-
tinue on to the Ot4 parameter. Do the same for this parameter also.
Press the Display key to exit the Setup menu.
If you return to the System menu, Ent3 and Ent4 are visible, and can be
turned on or off from here. Ent3 and Ent4 can also be viewed under the
StPt (Set Point) and SoAH (Soak) parameters in the Program Menu. Select
the correct jumper for contact closed with event ON (NO) or contact
open with event ON (NC).
See Chapter 8.
Guaranteed Soak Deviation
The Series 981/982 Guaranteed Soak Deviation (gSd) feature insures that
the actual temperature tracks a programmed profile within a window
around set point. See the example below. If the deviation is exceeded,
the time clock stops and the lower display alternately flashes gSd and the
current parameter until the process variable returns within the window.
Programmed in degrees or units, gSd is located in the Setup-gLbL menu.
Entering a value of (0) disables the Guaranteed Soak Deviation function.
Entering a value greater than zero sets up a plus and minus deviation
about set point.
