3.10 Password Protection
Parameter
1
2
3
Each setpoint may be protected from change using a four digit
password. Setpoints can be examined or changed, depending on the
status of password protection. When password protection is invoked
(see Figure 3-4), the setpoint may be changed using the password. The
setpoint can be examined, but not changed, by anyone that doesn't
know the password.

Description
X.0 x 10
r
Primary setpoint control value. Setpoint is inactive ifX = 0.
X.Ox 10-Y Hysteresis control. If X
=t:-
0, this parameter determines the point
ABCD
at which the setpoint turns off. Parameter 1 should be less in
value than parameter 2.
Control parameter
A= 0 (pressure), 1 (current)
B = 0 (no password required), 1 (password required)
C = 0 (HV interlock enabled), 1 ( disabled)
D 0 (not used, should always be 0)
When the setpoint is not under password protection, it can be changed
any time by anyone. Password protection can be invoked for an
unprotected password simply by changing a digit in parameter 3 (see
Figure 3-4). It is not necessary to know the password to invoke
password protection.
However, the procedure to remove protection from a setpoint requires
use of the password. If there is no record of the password necessary to
remove the protection, contact your customer service representative.
