Brief description of the stop gate devices

Refer to

Figure 4

and

Figure 9

Gate 0 – (G0) is located on the APS Track and is operated by

electro valve EV1. This Type 3 gate operates when the carrier

moving along the APS main track is either diverted into the

i2000SR IM or continues along the APS track. If the carrier is

diverted, Gate 0 and the standard track diverter (D0) activate to

route the carrier to the IM. The diverter (D0) is operated by

electro valve EV2.

Gate 0 is also used to maintain the number of carriers in the

queue of the i2000SR IM instrument interface.

NOTE:

The number of carriers queued at the Instrument Gate (G0)

is set by the value in the Instrument Gate parameter of the

Config Wizard Track Layout. The value of the standard

instrument interface queue is ten (10).

Gate 1 – (G1) is the Entry gate and is located on the Pit Stop lane

of the APS track and is operated by electro valve EV3. This Type 1

gate operates when the i2000SR IM is used with the APS. The

gate is normally closed and will only open to allow carriers from

the track to enter Lane 1 when there is no possibility that it would

interfere with an Off-line carrier from the IM lane 3.

NOTE:

The number of carriers queued at the Entry Gate (G1) is set

by the value in the Return/Entry Gate parameter of the

Config Wizard Track Layout screen. Typically the value is

set to eight (8) as that is the number of carriers that can

physically be placed in the area. (Refer to figure 1)
