KEYPAD OPERATION
The front panel of the M–Traverse is an easy to use keypad that gives you direct
access to the Parameters (Control Parameters and Monitor Variables) by entering the
Parameter Code. You can also use the keypad to change the value of a Control
Parameter. The keypad has keys for Code Select, Enter and Clear. It also has
numeric keys and four dedicated keys: Setpoint, Tach, Status and Batch Count. The
LED display is the above the keys. Refer to figure 3-1 for the location of the keys and
LED display on the keypad. Table 3-1 demonstrates basic keypad entry.
The keypad functions as follows:
Code Select Use the “Code Select” key prior to entering a Parameter Code
for either a Control Parameter (CP) or Monitor Variable (MV).
Numeric Use the numeric keys to enter a Parameter Code for either a
Control Parameter (CP) or a Monitor Variable (MV) or to enter
a value for a Control Parameter. Use the “Clear” key to delete
your entry. Use the “Enter” key after each entry, to enter it in
the M-Traverse.
—/Alt Use the “—/Alt” key to enter a negative value. In MVs 43, 44,
80, 81 and 84, the “—/Alt” key toggles between four lower and
four higher digits because some numbers exceed the six digit
display panel limit.
.
Use the decimal key for values with a decimal point.
Clear The “Clear” key will delete the entry, if you have not used the
“Enter” key.
Tach The “Tach” key is a dedicated or shortcut key. You can access
the tach Parameters directly, rather than manually entering the
Parameter Code (MV-40).
Setpoint The “Setpoint” Key is a dedicated or shortcut key. You can
directly access the active setpoint in the Follower mode (either
CP-01, CP-03, CP-05 or CP-07) or the active setpoint in the
Direct mode (CP-62).
