Curtis PMC 1223/33, 1225/35, 1227/37 Manual

The two CHANGE VALUE arrow keys are used to increase or decrease the value of a

selected menu item. Like the SCROLL DISPLAY arrow keys, the CHANGE VALUE arrow

keys can be pressed repeatedly or be held down. The longer a key is held, the faster

the parameter changes. This allows rapid changing of any parameter.

An LED on each CHANGE VALUE arrow key indicates whether the key is

active and whether change is permissible. When the value of a parameter is being

increased, the LED on the “up” CHANGE VALUE key is on until you reach the

maximum value for that parameter. When the LED goes off, you cannot increase

the value.

The MORE INFO key has three functions: (1) to display more information about the

selected item, (2) to access the Special Program and Special Diagnostics modes

(when used together with the PROGRAM and DIAGNOSTICS keys), and (3) to ini-

tiate certain commands (such as the Self Test).

“More information” is available in all of the programmer operating modes.

After using the MORE INFO key to display additional information about the

selected item, press the MORE INFO key again to return to the original list.

OPERATING MODES:

PROGRAM, TEST, DIAGNOSTICS, SPECIAL PROGRAM, SPECIAL DIAGNOSTICS

In the Program mode, accessed by pressing the PROGRAM key, all the adjustable

parameters and features of the controller are displayed (four at a time), along with

their present settings. The setting of the selected item—the item at the top of the

display, with the flashing arrow—can be changed, using the two CHANGE VALUE

keys.

The LEDs on these keys indicate whether there is still room for change. That

is, when the upper limit of a parameter’s range is reached, the LED on the “up”

key no longer lights up, indicating that the present value cannot be increased;

when the lower limit is reached, the LED on the “down” key no longer lights up.

The MORE INFO key, when used in the Program mode, displays a bar graph

along with the minimum and maximum values possible for the selected param-

eter. Parameters can be changed either from the main Program Menu or after

the MORE INFO key has been pressed and the additional information is being

displayed (see example below).
