HARDWARE TESTS / KEYPAD P2/3
Use the Hardware Tests / Keypad (page 2) to test the keypad. Press the Enter key to start the test. The
“START” text on the first line of screen will change to “EXIT” and you can begin testing the keys (with the
exception of the Enter key). Press each key individually. Each of the keys should register a number in the
Keypad Buffer line that corresponds with the numbers listed in Figure 8-1. A key has failed the test if its
number does not correspond with the numbers that are listed in Figure 8-1. Press the Enter key to exit the
test.
KeyPad Lockout
Keypad Lockout (MP-103) displays the Keypad Lockout status. The Keypad Lockout is active when
“On” is displayed. When Keypad Lockout is active, Control Parameter values can not be changed, with
the exception of the Control Parameters that are exempted by CP’s 480-489. The Keypad Lockout is not
active when “OFF” is displayed. When the Keypad Lockout is not active, any Control Parameter can be
changed.
