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] .
