The Form 4C control’s three-level security system limits
personnel access to only those control functions appro-
priate to their responsibilities. The four-digit security
code prohibits unauthorized keyboard access to pro-
gramming and operating parameters. No programming
commands are accepted by the control unless the oper-
ator enters the appropriate four-digit security code. Be
sure the necessary security codes are available to pro-
gramming personnel.
Interrogation of the control to display all operating para-
meters and read-only functions of the control panel does
not require entering a security code.
Note: Turning off the display at the keyboard removes any
security code previously entered via the keyboard.
Any security level entered is disabled 10 minutes after
keying in the last instruction or interrogation.
During programming, if identical codes are selected for
different security levels, the higher security level code is
recognized by the control.
First Level Security
First level security authorizes changes to the following
operating parameters:
• Minimum trip values
• Number of operations to lockout
• Time–current curves
• Reclose time
• Current-transformer selection
• Supervisory close reset time
• Phase identification
• Feature ON/OFF commands
• Selection of metering integration intervals
• Access to TCC timing groups
• Activation of Sensitive Ground/Earth Fault, High-
Current Trip, and High-Current Lockout
• Event Recorder
• Duty Cycle Monitor Factor
Second Level Security
The second level allows modification of these parame-
ters:
• Set control identification number
• Close retry time and number of attempts
• Operations counter
Third Level Security
The third level allows changes to these parameters:
• Security codes for levels 1, 2, and 3
• Line frequency
Factory Programmed Security
Codes
The Form 4C is programmed at the factory with stan-
dard security codes for first (1111), second (2222), and
third (3333) level security. These codes are changeable
to any four-digit number using the third level security.

CONTROL SECURITY
IMPORTANT: These security levels are designed to
be accessible only to personnel completely familiar
with the operation of these functions. Faulty program-
ming could lead to unintentional control performance.
