Lockouts Parameter 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, dEv, Hcur, UdSP and bdSP)
The contents of the secondary display can be changed in the Normal
Display Mode by successively pressing the D button. This action scrolls through the possible display parameters, when enabled. If all parameters are set to lock “LOC”, press D to blank the display.
The parameters 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 lower display content possibilities are:
SP – Setpoint Value
OP dEv
UdSP bdSP
Hcur
– % Output Power
– Setpoint Deviation
*
– Temperature Units (T48)
– Blank Display (P48)
– Heater Current Readout*
* Models equipped with Heater Current Option replace “DEv” (Deviation) readout with “Hcur” (Heater current readout).
Note: If a parameter is active in the lower display and is then subsequently locked out, press “D” once in the Normal Display Mode to remove it from the display.
Protected Mode Lockouts (CodE, PId, and AL)
The protected mode is active when program disable is active. The parameters in the protected mode can be set for one of the following modes:
LOC (Lockout) – Prevents the parameter from appearing in the protected mode.
rEd (Read only) – Parameter appears, but cannot be modified.
-38-
Ent (Entry) – Parameter appears and can be modified.
The code number allows access to the unprotected mode. To enter the unprotected mode from the protected mode, the code number entered must match the code number entered here. See Front Panel Program Disable, page
17, for a description of the various program access levels.
CodE
PId
AL
– 0 to 250
– Permits access to the main PID parameters.
– Permits access to the alarm value(s).
Hidden Mode Lockouts (ALrS, SPSL, trnF, and tUNE )
The hidden mode is accessible from the Normal Display Mode by pressing and holding the P button for three seconds. The parameters can be set for:
LOC (Lockout) – Prevents the parameter from appearing in the hidden mode.
ENbL (Enable) – Allows operator to perform the selected hidden mode function.
The functions available in the hidden mode are accessible independent of the status of program disable.
ALrS
SPSL trnF tUNE
– Reset (override) the alarm output(s).
– SP1/SP2/Remote setpoint selection.
**
– Select Automatic or Manual operation.
– Invoke or cancel Auto-Tune.
** Model Number Dependent.
