Length of time to allow for legs lower at start of ASQ; legs must reach Advancing Pressure during this time. •••Advancing Pressure

Range: 50-150 Def: 80

Legs must get down to this pressure or less during Initial Lowering time or shield advance is not allowed and ASQ will fail.

•••Contact Advance

Options: OFF, ON Def: OFF

When Contact Advance is On, the Initial Lowering stops as soon as the legs reach Advancing Pressure. Generally, the leg lower function will be released and the shield advance function activated immediately. To continue lowering for some time while the shield is advancing, set Extra Lowering Time greater than 0. To allow some of the extra lowering to occur before activating the shield advance function, also set Advance Delay Time greater than 0. For faster ASQ & less fluid use, set to Contact Advance to On; for better baselift & less top contact set to Off. For some of both Set Contact Advance to On, Extra Lowering Time to 100-300 and Advance Delay Time to 50-100. •••Extra Lowering Time

Drop baselift when shield reaches this stroke while advancing; used to reduce chance of shield toes hitting cable trough on conveyor.

•••Baselift During Adv

Options: OFF, ON Def: ON

Option to activate baselift while shield is advancing; if this is On and Baselift During Lower is Off, then Pre-Baselift Time applies. •••Maximum Advancing Time

Range: 0-1500 Def: 800

Maximum time allowed for shield advance. This should be set to approximately twice the time normally required for a shield to fully advance. The shield advance normally stops when the ram stroke reading reaches the target stroke set by parameter Advancing Tgt Stroke. This time setting is for cases when the ram sensor is invalid or ignored. •••Advancing Tgt Stroke

Range: 2-100 Def: 2

Shield stops advance at this ramstroke reading. This is usually set on 2 so shield will advance completely but not error-out if the ram stroke reading doesn't go completely to 0. This can be set to higher numbers to partially advance shields. •••Retry Count

Range: 0-3 Def: 3

Sets number of retries that will be made if shield fails to advance to Advancing Tgt Stroke within time set by Maximum Advancing Time; retries consist of more leg lowering for time set by Relowering Time and another advance attempt limited by Max Readvance Time. To avoid failed ASQ, recommended min for this parameter is 1. To avoid excessive lowering, recommended max for this paraemter is 2. •••Tip Down on Retry

Range: 0-3 Def: 2

Sets which retry attempt will also activate tip down function to reduce roof contact; ex: if set on 2 then second retry attempt will operate tip down function for Tip Down Time before readvancing.

•••Tip Down Time

Range: 0-200 Def: 50

Length of time for tip down function activated by Tip Down on Retry parameter. •••Relowering Time

Range: 0-500 Def: 200

Length of time for leg lower function as part of retry. The leg pressure readings are not used - this is a time-only function!. If this time is set too high and the Retry Count is too high, the shield could lower completely to pan line. The recommended setting is 100-200.

•••Float Canopy While Setting

Options: OFF, ON Def: ON

When On, canopy float valve will be activated while the shield is setting. •••Final Set Time

•••Ram Refill Time

Range: 0-150 Def: 40

Length of time for ram push fct to stay active at end of ASQ to tighten clevis connection. Activates once legs reach 50 bar. Typically set to 25 - 50. •••Next Advance Tgt Stk

Range: 0-100 Def: 0

Overrides Advancing Tgt Stroke on next ASQ; usually 0 - it gets set to calculated number when a Wedge Advance is programmed. •••HG Seq First Shield

Range: 1-15 Def: 4

Shields between HG Seq First Shield and HG Seq Last Shield pull sequentially, beginning with HG Seq First Shield. This allows gate shields and transition shields to be advanced in correct order. If there are 3 actual headgate shields and 1 actual transition shield, HG Seq First Shield should be set on 3 and HG Seq Last Shield should be set on 5 so that #3 pulls first, followed by #4 and finally #5. This prevents #5 from pulling before #4 and prevents #4 from pulling before #3. #1 and #2 can pull in either order since they are both gate shields. This does allow #1 and #3 to pull at the same time. If this is not desirable, HG Seq First Shield can be set on #1 then shields 1 - 5 will all pull sequentially. •••HG Seq Last Shield See description above.

Range: 1-15 Def: 6

•••TG Seq First Shield

Range: 1-15 Def: 3

Shields between TG Seq First Shield and TG Seq Last Shield pull sequentially, beginning with TG Seq First Shield. This allows gate shields and transition shields to be advanced © Caterpillar

in correct order. Both values are measured as the number of shields from the tailgate instead of actual shield numbers. If there are 3 actual tailgate shields and 1 actual transition shield, TG Seq First Shield should be set on 3 and TG Seq Last Shield should be set on 5 so that the third shield from the end pulls first, followed by the fourth and finally the fifth from the end. •••TG Seq Last Shield

Range: 1-15 Def: 7

Can only be switched from Off to On. To switch Off, toggle another tracking mode to On. ••Serial Tracking Type Use this parameter to switch between CAT and Joy shearer type communication to the PLC. PMCP = CAT. PLC = Joy

••Endgate Integration

Options: OFF, ON Def: OFF

Endgate integration allows the shield system to communicate to the shearer to pause tramming during turnarounds until the shields have caught up. This allows full automation of the shearer which includes fixed turnpoints. Since the turnpoints are fixed, the shearer cannot change the length of the double cut if it turned around before the shield system was caught up. Instead, it will stop tramming and wait until the final shield has pulled. ••Beginning Shield First shield on face that SRB will control.

••or press Enter

The Umbrella Lock feature creates a safe travel way to allow operators to move through areas where shields would normally be moving without altering the mining cycle. Pressing the Umbrella Key (5) for 3s activates the Umbrella Lock Zone; it extends on both sides of initiating shield. In this zone, shields can push but not advance. If a shield in the Umbrella Lock Zone is triggered to ASQ, the ASQ is paused; if the Umbrella Lock Zone is removed from the shield soon enough, the ASQ will then become active and advance the shield. This lets people move through areas where shields should be moving without danger and without screwing up the mining cycle. ••To clear ULock hold 3s

••or press Enter

When the Umbrella Lock Key (5) is pressed on the center shield of the Umbrella Lock Zone, this display prompts the operator to hold the key for 3s to cancel the zone. Removing the Umbrella Lock Zone may allow shields to complete a previously triggered advance. There is a notice beeper sound throughout the zone and a 3s delay before any ASQs will start, in addition to the normal ASQ prewarning. ••Umbrella activated.

••Not for maintenance!!

Umbrella lock is for travel only - not maintenance. For maintenance, the shield should be locked out using the PMC-R's black lockout button, and the maintenance lock should be used. Maintenance lock is setup by pressing 5 and then holding the 0 key. The shield should also be isolated hydraulically during maintenance. ••Umbrella activated.

••For travel only!!
