Watlow PM LEGACY™ Limit Controller • 93 • Chapter 8 Features
Another example of Method 1 lockout usage could be that an operator wants read access to all pages
while allowing read/write access to the Home Page and the Lockout Menu only. To setup this scenar-
io follow the steps below:
1. From the Home Page, press and hold the Reset Key and the Advance Key for approximately six sec-
onds. CUst will appear in the upper display and fCty will appear in the lower display.
2. Press the Up Key until LoC appears in the upper display and fCty will appear in the lower display.
3. Press the Advance Key until Read Lock rLoC appears in the bottom display and change it to 5.
4. Press the Advance Key until Set Lock SLoC appears in the bottom display and change it to 1.
Although the Factory Page is always visible, some menus within it can be restricted.

* Using lockout Method 1 with SLoC set to 0, all writable parameters within the control will be inhib-
ited (not writable) with two exceptions, SLoC and rLoC. As shown below, both of these parame-
ters can always be seen and modified.

Note: Using Method 1 Lockout all settings can be modified by anyone who knows how to find their
way to the SLo C and rLoC parameters.
Using Lockout Method 2 (Password Enable)
It is sometimes desirable to apply a higher level of security to the control where a password would be
required to access the control. If Password Enabled pas .E in the Factory Page under the Lo C Menu is
set to on, an overriding Password Security will be in effect. Without the appropriate password, spec-
ified menus will remain inaccessible. Page and Menu access is defined in the Locked Access Level
Lo C. L prompt. On the other hand, a User with a password would have visibility restricted by the
Read Lockout Security rLoC. As an example, with Password Enabled and the Locked Access Level
LoC.L set to 1 and rLo C is set to 3, the available Pages for a User without a password would be lim-
ited to the Home and Factory Pages (locked level 1). If the User password is entered all pages would
be accessible with the exception of the Setup Page as defined by level 3 access.
