- 1 x 19“ frame MMS 6352

- 6 x screw terminal MMS 6361

- 6 x cable 0.5 m MMS 6362

alternatively

cable 3 m MMS 6360

- 1 configuration kit MMS 6950

3 x blind plates BLE 008, for

the installation of monitors without

display

When using this system line,

there are additional combinations

available via relay outputs beside

the normal outputs of the alarms

OUT1....OUT6 and the system

supervision Channel Clear:

2 v 3 combination output OUT2

2 v 3 combination output OUT4

OUT5 (= TRIP+CC) channel A

OUT5 (= TRIP+CC) channel B

OUT5 (= TRIP+CC) channel C

System DOPS TS

This system line is used to replace

AEG-Turloop systems.

For the redesign on this system, the

speed monitors MMG 1222 TS are

removed from the slots and

replaced by MMS 6350+MMS 6353

each.

The old, existent Turloop frame

remains in the rack, it is not

necessary to change the wiring.

The following components are

required:

- 3 x monitor MMS 6350 (incl.

firmware appl. no. 1)

In addition:

3 x adapter MMS 6353 TS

- 1 configuration kit MMS 6950

- 1 set of blind plates MMS 6354

The DOPS TS system replaces

the functions of the old Turloop

system. With this system line not

all functions of DOPS or DOPS

AS are at disposal.

The DOPS TS system is not

certified according to SIL3, DIN

EN 61508.

The Profibus-interface is not

available for system line DOPS

TS.

Module supervision

Sensor supervision

All three DOPS system lines offer the

same extensive system supervision

functions.

Reasons for module disturbances

can be read out in detail via the

communication interface or, at

modules with a display, directly on

the display.

This permits the technicians to

recognize the reason for the fault

immediately.

During the change from the error to

the ok-state and after power-on of the

module, all functions of the module

are blocked for a delay time of 5 sec.

Depending on the backplane used

or the installed firmware, the

indication of faults or overspeeds is

made via function-outputs and beside

this via relay outputs with 2 out of 3

combinations of the alarm outputs.

The systems DOPS and DOPS AS

offer the following supervision

functions:
