SPEEDTRONICTM MARK V HARDWARE

CABINET (CASE)

Size

TMR = Triple Modular Redundant cabinet size

(54"w x 20"d x 90"h).

Simplex = cabinet size (36"w x 20"d x 90"h).

Grounding

The cabinet is equipped with a ground bar and

lug which must be connected to the plant's

ground grid system or earth ground with a

minimum #4 AWG cable size. This cable is for

electrical grounding and noise interference

reduction. The cable resistance should be no

greater than 1/2 ohm.

Radio transmitters

Operation of a 5 watt or less radio transmitter

at 27 MHz, 150 MHz and 480 MHz with panel

doors closed will not disrupt control operation.

If at all practical, try not to key radio

transmitters near the control panel.

Power requirements

100 - 144 VDC at a minimum of 7 amps. Add

0.5 amps for each solenoid used.

108 - 132 VAC at a minimum of 7 amps. Add

6 amps for each ignition transformer used (2

maximum) and 0.5 amps continuous (3 amps

inrush) for each AC solenoid used.

216 - 264 VAC at a minimum of 3.5 amps.

Add 3.5 amps for each ignition transformer

used (2 maximum) and 0.5 amps continuous (3

amps inrush) for each AC solenoid used.

Layout

Figure 1 is a functional layout of the MK V

cabinet showing the location of the different

cores and their relationship with the I/O

terminations.

Figure 2 is a descriptive layout of the MK V

cabinet showing the actual card and I/O

locations within the different cores.

Back up panel

The back operator interface , (Figure 3)

is located on the right front door. The back up

operator interface provides access to control

and monitoring functions for the operator,

allowing continuous operation of the turbine if

the main operator interface fails. The

is connected directly to , , and .

E-stop

The E-Stop (emergency stop) push-button is

located below the back up panel on the right

front door (Figure 1). This push-button is used

to trip the turbine in an emergency situation

only and should not be used as a normal

turbine stop. (Note: Steam turbine applications

use this as the last step of a normal shutdown)

Cores There are at usually 8 different cores used in

the gas turbine and steam turbine control

system for TMR panels (6 for a simplex

panel.) Additional cores are added as required

by the application.

******** CAUTION ********

It is not required to remove power from the

cores when pulling out the card carriers. Be

careful not to touch any of the components

while doing this. If you must remove power

from the core, remove the power cable or use

the switches in the core. DO NOT

remove the fuse.
