Model OMM-1

Output Master Module

INTRODUCTION

The Model OMM-1 Output Master Module from Siemens Industry,

Inc., is the motherboard for all of the MXLV plug-in boards: the OCC-

1, ASC-1/-2, PLC-4, RCM-1, ZAC-30, and the ZC zone cards. The

module has the same dimensions as the MOM-4 MXL motherboard.

The OMM-1 mounts vertically in the backbox and contains four half-

width card slots. (Refer to Figure 1.)

All field wiring terminates on the OMM-1 terminal blocks. (See Figure

4.) Power and network communications are provided by the MMB or

the PSR-1, depending on the application. The network control

signals are distributed to the plug-in cards through the OMM-1. All

connecting cables are supplied with the unit.

The MME-3 enclosure has three locations for the OMM-1s (or for

OMM-2s, MOM-4s, or MOM-2s). However, when a TSP-40 printer

is installed in an enclosure, the total number of OMMs is decreased

to two modules for that enclosure. The MLE-6 enclosure has six

locations for optional card cages, such as OMM-1s, OMM-2s,

MOM-4s, or MOM-2s.

INSTALLATION

(Refer to Figures 2 and 3.)

Remove all system power before installation, first the

battery and then AC. (To power up, connect the AC first, then

the battery.)

Unpack the OMM-1 and its attached backplate. Inspect it, looking

for such things as connectors not properly installed, missing polar-

izing keys, dirt, and packing material on the board.

Check to see if the card guides for the plug-in boards are already

installed. If they are not, install all eight of the card guides accord-

ing to the following directions before mounting the OMM-1 into the

enclosure.

To install the card guides:

(Refer to Figure 2)

1. Place the card guide shoulder on the

raised boss at the end of the card edge

connector.

2. Align the hole in the shoulder with the hole

in the boss.

3. Place the mounting screw in the hole in

the shoulder and tighten the screw.

4. Repeat Steps 1, 2, and 3 for the

remaining card guides.

To mount the OMM-1 card cage:

The OMM-1 mounts vertically in the enclosure

under the MMB or the PSR as shown in

Figure 3.

The installation kit for the OMM-1 includes the

following:

• Four No.10 nuts

• Four washers

• One 8 conductor ribbon cable

(P/N 555-190967)

• One 14 conductor ribbon cable

(P/N 555-192155)

1. Hold the OMM-1 so that the two position

terminal block TB1 is at the top. (See

Figure 1.)

2. Place the module on the mounting studs in

the left-hand position of the enclosure as

shown in Figure 3.

3. Fasten the OMM-1 in position with the

No.10 nuts and washers provided.

4. To mount any other OMM-1 modules

used in the system, repeat the above

steps. Use the center or right-hand

position for the additional modules as

needed.

5. When mounting OMM-1 modules in an

MLE-6 enclosure, it may be necessary to

reverse the mounting in the lower row by

placing the two position terminal block

TB1 at the bottom instead of the top

(Refer to Figure 5). This will insure that

the 14-conductor cables that are supplied

can be assembled.

To assign plug-in cards to the OMM-1:

The cards that can be assigned to plug into

the OMM-1 are the OCC-1, the ASC-1/-2, the

PLC-4, the RCM-1, the ZAC-30, and the ZC

zone cards. Determine which optional plug-in

cards are used in your CSG-M configuration.

Assign the plug-in cards to the card edge

connectors on the

OMM-1(s) as needed.

Figure 3

Mounting the OMM-1 Board

It may be necessary to reverse the module

mounting in the lower row of the MLE-6

enclosure to insure that the 14-conductor

cables that are supplied can be assembled

(See Figure 5).

5. Note that there are two eight conductor

cables. The long eight conductor cable

(P/N 555-192243) comes with the ACM-1.

Use this cable for communications and

power from P4 on the OMM-1 to either P6

on the PSR or to P6 on the MMB,

whichever is present.

This cable is polarized. Observe polarity

and DO NOT USE EXCESSIVE FORCE.

The black tracer on the cable indicates

the position of pin 1.

6. If there is more than one OMM-1, use the

short eight conductor cable (P/N 555-

190967) to connect P3 of the left-hand

OMM-1 to P4 of the OMM-1 that is to its

right.

This cable is polarized. Observe polarity

and DO NOT USE EXCESSIVE FORCE.

The black tracer on the cable indicates

the location of pin 1. If there are more

OMM-1s in the system, repeat this step.

For additional information on the

MXLV System, refer to the MXLV

Manual, P/N 315-092036.

CAUTION

Handle all plug-in cards with extreme care.

When inserting or removing a card, keep

the position of the card at right angles to

the OMM-1 board. Otherwise, the plug-in

card can damage or displace other com-

ponents. Never insert or remove a plug-in

card with power applied to the panel.

WIRING

(Refer to Figures 4 and 5)

All wiring must comply with

national and local codes.

1. When the 24 VDC is provided by either

the MMB-2/-3 or SMB-2 or PSR-1, use

TB1 on the OMM-1 to connect the power.

The wire for this connection is not

supplied (See MMB-2 Installation

Instructions, P/N 315-095097, or MMB-3

Installation Instructions, P/N 315-048860,

or SMB-2 Installation Instructions, P/N

315-095931, or PSR-1 Installation

Instructions, P/N 315-090911, for terminal

connections.)

2. Assign plug-in cards to the card edge

connectors as determined above. Once

the terminal block related to each edge

connector is wired, place only the

assigned plug-in card in that edge

connector.

3. Refer to the Installation Instructions listed

in Table 1 for directions on wiring to the

22 position OMM-1 terminal blocks and

for attaching these modules to the OMM-1

terminal blocks.

4. If the system includes more than one

OMM-1, use the fourteen conductor

ribbon cable (P/N 555-192155) to connect

P1 of the first OMM-1 to P2 of the second

OMM-1. If there is a third OMM-1,

connect P1 of the second OMM-1 to P2 of

the third OMM-1. No more than three

OMM-1s can be connected together when

they are installed in an MME-3 enclosure.
