LOCKOUTS MODULE (3-LC)
The controller can be programmed to limit operator access to various
parameters, control modes, and display contents. The configuration of the
lockouts is grouped into three sections: Lower Display Lockouts, Protected
Mode Lockouts and Hidden Mode Lockouts.
Lower Display Lockouts (SP, OP, P-cs, P-tr, UdSP)
The contents of the secondary display can be changed in the normal display
mode by successively pressing the DSP button. This scrolls through the four
possible display parameters, if enabled. Each parameter can be set for one of
the following:
LOC (Lockout) - Prevents the parameter from appearing in the
secondary display.
rEd (Read only) - Parameter appears, but cannot be modified.
Ent (Entry) - Parameter appears and can be modified.
The five lower display content possibilities are:
SP - Setpoint Value
OP - % Output Power
P-CS - Profile Control Status
P-tr - Profile Phase Time Remaining
UdSP - Temperature Units
If all parameters are set to lock “LOC”, the display will remain on the last
parameter that was viewed.
Note: If a parameter is active in the lower display and then subsequently
locked out, press “DSP” once in the normal display mode to remove it from
the display.
Protected Mode Lockouts (Code, PID, & AL)
The protected mode is active when program disable is active. The PID and
Alarm parameters can be set for one of the following:
LOC (Lockout) - Prevents the parameter from appearing in the display
rEd (Read only) - Parameter appears, but cannot be modified.
Ent (Entry) - Parameter appears and can be modified.
The PID setting allows access to Proportional Band (ProP), Integral Time
(Intt), and Derivative Time (dErt) parameters. Alarm 1 and 2 values (AL1 &
AL2) may also be locked out if installed.
A code number to enter the unprotected mode can be programmed into the
controller. To enter the unprotected mode from the protected mode, the code
number must match the code number entered. Refer to front panel program
disable section for access levels.
Code - 0 to 250
Hidden Mode Lockouts (ALrS, CPAC, PrAC, trnF, & tUNE)
The hidden mode is accessible from the normal display mode by pressing
and holding the PAR button for three seconds. The parameters can be set for:
LOC (Lockout) - Prevents the parameter from appearing in the display.
ENbL (Enable) - Allows operator to perform function.
The five controller functions are executed in hidden mode and are
accessible independent of the status of program disable.
ALrs - Reset (override) an alarm/timed event output(s).
trnF - Transfer controller from or to automatic to manual operation.
CPAC - Load 1 of the 4 control points (CP).
PrAC - Allows the operator to start one of the 4 profiles.
If a profile is running, the status (Adnc, Cont, PAUS, or OFF)
can be changed.
tUNE - Invoke or cancel Auto-Tune.
