Key Lockout Information
The Series 935B offers three different security, or “lockout,” options. Set up
one or all three lockout options in the Configuration Menu.
• Front Panel Lock [`FPL] uses an input for an external hardware switch;
it requires wiring, see p. 25. Choose Front Panel Lock [`FPL] from the
[`rts] choices.
• Choose Set Point Lock [SLOC] as the simplest lockout option. It locks
the Primary Set Point from change, but not from view.
• Choose the Security Tag [`tAG] as a means of masking the Series
935B software menus from view. By selecting all or part of the four-digit
binary acronym,
[PCOA] (Proportional / Configuration / Operation / Auto-
tune), you can choose to mask those items from view, and therefore from
change. For example: In the Configuration Menu
[`tAG] set-up, if you
can see the P, the operator cannot see the PID menu.
• Exceptions to [PCOA] [`tAG] are:
“C” does not lock out [`tAG] .
“O” does not lock out [CnFG] .
