DESCRIPTION
The PMC-R Shield Control Unit is an advanced digital shield control system. It is based on patented state-of-the-art electronics and contains multiple sub-processors, a dual line display, color coded keys, and a built-in infrared receiver. The PMC-R is capable of operating in a network of hundreds of units and utilizes modern software concepts to maximize the effectiveness of the computing and communications hardware. The PMC-R is housed in a stainless steel watertight enclosure that will hold up to most underground situations.
The keys are color coded to match the type of purpose they serve.

DISPLAY
The PMC-R Display is a backlit LCD display with 2 lines of 22 characters each.
Display Categories
The following display categories exist:
Default Display: no keys pressed; no shield function is occurring
Active Display: shield function (such as Bankpush) is active
Master Display: operator has selected another shield for manual operation
Slave Display: this shield is selected for manual operation
Input Display: operator is entering numerical values
Default Display
The Default Display is shown when the PMC-R is not operating any other function.
#129 317 105>I 100% 180
"#129" is the shield number.
"317" is the leg pressure in bar.
"105>" is the Shearer Position & Direction.
"I" indicates "Infrared" shearer tracking is in use. An "S" would indicate serial tracking. An "M" would indicate manual shearer tracking.
"100%" is the Ram Stroke in percent.
"180" is the Leg Pressure to your right in bar.
An "i" preceding any sensor reading indicates the sensor is being ignored because it is turned Off under the Sensor Status section of the menu.
Any invalid value will be displayed as "~~~" instead of a number.
Active Display
The Active Display is shown when the shield is executing a function. The details vary depending on the function which is active. Generally, functions will leave the bottom line of the default display and display status information on the top line with the name of the function surrounded by “!”. For example, this shows an active ASQ function in the Warning state: ! ASQ ! * WARNING *
317 105>I 100% ~~~ © Caterpillar
2
Note also that the last value on the bottom line is invalid causing it to be displayed as “~~~”.
Master Display
When an operator uses the PMC-R on one shield to control another shield manually, the shield where the operator is pressing keys is called the Master and the Master Display will be shown. Although most hydraulic functions can be activated using the dark blue “man-in-place function keys” there may be other hydraulic functions available. These are called Auxiliary Functions and are shown in the display where they are controlled using the N & P arrow keys.
For example, the Canopy Spray line allows the operator to control the canopy spray function by pressing and holding the P-key (the arrow below the “ON” text).
8: Canopy Spray
From the Master Display, available Auxiliary Functions are accessed by using the Menu Navigation keys to scroll up or down.
Slave Display
The Slave Display is shown on a shield that has been selected from another shield. # 3 ! Slave ! - # 1
317 105>I 100% ~~~
The top line indicates that the shield is being operated as a slave unit. It shows that this is shield #3 and it is being controlled by shield #1.
The bottom line continues to show the default display of sensor values and shearer position.
Input Display
When an operator is entering a numerical value the display is in Input Mode and will show the name of the value being entered and a question mark, similar to this:
Abort Dist
Input Mode terminates when the Enter key is pressed or, if no keys are pressed, after a several second timeout.
ON

KEYS
General Key Concepts
Audible Feedback
When any key is pressed there is audible feedback. If it is a valid keystroke, there will be a single short beep. If it is an invalid keystroke, there will be an "error beep" which is 3 consecutive short beeps.
Timeout
When no key has been pressed for the 4s, the display will timeout and revert to the Default Display Mode and any manual actions will be canceled (e.g., Master Mode, menu scrolling).
Stuck Key Error
If a key is held for more than 60s continuously, the key will be considered "stuck", an error sound will occur, and an error will be posted.
(err: "KEYBOARD ERROR stuck key")
Multiple Key Error
If an invalid combination or sequence of keys is pressed an error sound will occur and an error will be posted.
(err: "KEYBOARD ERROR bad key combination")
Keyboard Modes
Beep and Error-Beep
Don’t wait too long!
Don’t hold keys too long!
Don't press too many keys at once!
Some PMC-R keys have only one function (e.g., the Stop key). But most keys have multiple functions (e.g., the 2-key is also the Positive Set key). The keyboard mode determines what the multi-function keys do when they are pressed.
Idle Mode
When nothing else is going on.
©
Idle Mode is the normal mode when no keys are being pressed. When Menu Keys have been used to view different displays, the keyboard is still in the Idle Mode until an actual action has been taken. When any other mode times out, the Idle Mode is entered and the Default Display is shown. In Idle Mode, the man-in-place keys are shortcuts to various menu displays. 4
