Introduction
The MPS-TR Power Supply Monitor is an add-on board designed to mount on the right side of MPS series power supplies. It is fastened using two extended length standoffs that utilize the existing threads on the power supply's standoffs.
The MPS-TR monitor provides supervision for remote power supplies. Once mounted and secured, the P1 connector on the MPS-TR connects to the P3 connector on the power supply via a supplied power ribbon (part number 71085). The common (C) and normally closed (NC) contacts of the MPS-TR's Form C relay are intended for connection to the normally closed TROUBLE INPUT on modules such as the ACM-16AT, ACM-32A, or MMX-1.
Note: It is recommended to locate the power supply with the MPS-TR and the trouble transmitting device (e.g., ACM-16AT, ACM-32A, MMX-1) in the same room.
Installation
- Remove the upper and lower screws located on the right side of the power supply main board.
- Position the MPS-TR board over these two holes. Insert the new, longer screws through the MPS-TR board and through the provided standoff sleeves. Thread these screws into the holes previously occupied by the removed screws.
- Install a nylon standoff into the appropriate hole in the middle of the MPS-TR board. The specific hole required depends on the type of power supply being used and is labeled on the MPS-TR board. After selecting the correct hole, insert a screw into the standoff. Note that the threaded end of the nylon standoff does not screw into the power supply board; it serves only to keep the MPS-TR board from contacting system components. It effectively "stands" on the main power supply board. A nylon (non-conductive) standoff is used because it directly contacts the PC board.
Diagram Description: A visual representation shows the MPS-TR board being mounted onto an MPS Power Supply board. It depicts the MPS-TR board positioned above the power supply. Two new, longer screws pass through the MPS-TR board and standoff sleeves, threading into existing studs on the power supply board. A nylon standoff is shown in the middle of the MPS-TR board, resting on the power supply board to prevent contact. Labels include "New Screw", "Standoff", "MPS Power supply board", "Existing threaded stud", "MPS-TR Board", and "Mounting Hole (Keyhole slot for adjustment)".
Diagram Description: A detailed view of the MPS Series Power Supply (MPS-24A Shown) circuit board is presented, highlighting connectors (TB1, TB2, TB3), jumpers, fuses, and test points. Connection point P3 is indicated for the ribbon cable to the MPS-TR. A separate diagram shows the MPS-TR board with its P1 connector, labeled "Screw", "MPS-TR Board", and "Mounting Hole". A "Nylon Standoff" is depicted, noting it rests on the power supply board and does not screw in.
Applications and Wiring
The MPS-TR can be integrated with various Notifier modules for trouble monitoring. The following sections detail common applications and their respective wiring configurations.
Application: ACM-16AT, ACM-32A
The MPS-TR's common (C) and normally closed (NC) relay contacts connect to the normally closed TROUBLE INPUT on the ACM-16AT or ACM-32A module.
For the ACM-16AT, connect to Trouble input terminals 6 & 7 on TB1. It is recommended to remove any existing jumper on terminal 6 & 7 before connecting.
Diagram Description: Illustrates the ACM-16AT module with its terminal grid. It shows connections from the MPS-TR to "Trouble input terminals 6 & 7 on TB1" of the ACM-16AT, with a note to remove existing jumpers. Lines indicate connections for "To common and normally closed contacts" from the ACM-16AT to the MPS-TR.
Diagram Description: Depicts the Form C relay contacts of the MPS-TR in their normal (no trouble condition) state. Terminals shown are "Normally Closed", "Relay Common", and "Normally Open". Also indicated are "System Common" and "Common Terminal Connection".
Application: S5000, AM2020, AFP1010 (using MMX-1 Module)
The MMX-1 Module can be dedicated to trouble monitoring. It utilizes normally closed relay contacts that open upon trouble. These contacts are connected to the MPS-TR.
The connection involves the MMX-1 module's common and normally closed contacts being wired to the MPS-TR. An End of Line Resistor (ELR) is used in the SLC loop, with its value specified in the respective control panel documentation.
Diagram Description: Shows the MMX-1 Module application. It includes the SLC Loop with positive (+) and negative (-) terminals, and an End of Line Resistor. The MMX-1 module's normally closed relay contacts are used for trouble monitoring. Connections are made from the MMX-1's common and normally closed contacts to the MPS-TR.
Application: AM2020, AFP1010 (using MMX-101 Module)
The MMX-101 Module can also be used for trouble monitoring. It employs normally open contacts that close upon circuit trouble, configured for software type MTRB.
Connections are made from the MMX-101 module's common and normally open contacts to the MPS-TR. An End of Line Resistor (ELR) is part of the SLC loop configuration.
Diagram Description: Illustrates the MMX-101 Module application. It features the SLC Loop with (+) and (-) terminals and an End of Line Resistor. The MMX-101 module uses normally open contacts that close during trouble, set for software type MTRB. Connections are made from the MMX-101's common and normally open contacts to the MPS-TR.
Application: XP Transponder (using XPM-8 Circuit)
The MPS-TR can be integrated with an XP Transponder via an XPM-8 circuit. The connection utilizes a 2.2K resistor and connects the XPM-8 circuit to the MPS-TR's Normally Closed (NC) and Common (COM) terminals.
Diagram Description: Shows the XPM-8 Circuit application with the MPS-TR. It depicts the XPM-8 module, a 2.2K resistor, and the MPS-TR. Connections are illustrated from the XPM-8 circuit to the MPS-TR's "NC" (Normally Closed) and "COM" (Common) terminals.
