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" is the shield number.

"317" is the Leg Pressure to your left in bar.

"105>" is the Shearer Position & Direction.

"I" indicates "Infrared" shearer tracking is in use. A An "M" would indicate manual shearer tracking.

"100" is the Ram pressure.

"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% ~~~

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 Auxiliary valve line allows the operator to control an auxiliary function by pressing and holding the P-key (the arrow below the “AUX1” text).

31: Auxiliary Valve

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 0 317

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.

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.

Master Mode

Selecting a shield for control is the only way Master Mode is entered. This can only be done from the Idle Mode. In Master Mode, the dark blue man-in-place keys can be used to manually operate the selected shield.

Group Function Mode

The Group Function Mode is entered when any Group Function key is pressed. It may only be entered from the Idle Mode or if in neighbor select mode it changes to group function mode. After pressing the Group Function key, a group select key is usually pressed followed by the Start key to start the group function.

Data Entry Mode

The Data Entry Mode is entered when the Enter key is pressed to begin the process of changing a parameter and ends when the Enter key is pressed to finalize the parameter. In the Data Entry Mode, the numeric keys are used to enter numbers.

Help Mode

The Help Mode is activated when the Help key is pressed. The help text is then displayed and the only valid keys are the Help key (to exit Help mode and return to the previously displayed line), and the Menu Up and Menu Down keys (to scroll through the help text).

Specific Key Information

Press Help to… get help!

When pressed from the default display, the man-in-place keys are used as “hot keys”. The first time the key is pressed, one display is shown; if pressed again, another display is shown:

OperatorAssignedHotKey

When the A-key is pressed from the Default Display, the operator assigned display is shown. When pressed from any other display, the A-key is linked to the currently active display on this shield and for a range of +/- 5 shields. By default, it is linked to the PMC-R Voltage display.

Single Select Keys

The Single Select keys are generally used to select a single adjacent shield for control. After pressing the Single Select key, the adjacent shield is controlled manually via the man-in-place keys; optionally an Autosequence can then be started by pressing the Start key.

The Single Select keys are also known as the Shield Select keys or the Neighbor Select keys. H Key

This key will select the single neighbor shield to the immediate left. If followed by the Enter key, a remote shield (up to 5 away) can be selected for operation. See Remote Control on page 25
