EMERSON-5.32F1-Multi-Zone-Leak-Detector

Product Information: Multi-Zone Leak Detector

The Multi-Zone Leak Detector is a device designed to detect refrigerant leaks in multiple zones. It is equipped with audible and visible alarms that can be set based on user-defined alarm and spill setpoints. Each zone has the capability to trigger a circuit shutdown in the event of a spill. The Leak Detector Panel comes with a local strobe and horn, and optional hardware includes remote horn and strobes, MRLDS Halo-carbon and CO2 sensors, and battery backup panel.

Product Usage Instructions

Multi-Zone Leak Detector

Ensure that the Leak Detector firmware is version 5.35F01 or higher.
To view zone status screens, refer to page 13 of the user manual.
To configure parameters, refer to the table of parameters on page 14 of the user manual.
To upload the Multi-Zone Refrigerant Leak Detector Description File to E2, follow the steps on page 18 of the user manual.
To license the Multi-Zone Leak Detector in the E2 system, refer to page 19 of the user manual.
For device setup in the E2 system, follow the instructions on page 19 of the user manual.
Each zone is capable of operating an audible and visible alarm based on user-defined alarm and spill setpoints. Adjust these settings according to your requirements.
In the event of a spill, each zone has the ability to trigger a circuit shutdown. Ensure that this feature is enabled and properlyconfigured.
If necessary, install optional hardware such as remote horn and strobes, MRLDS Halo-carbon and CO2 sensors, or battery backup panel.

For detailed information and step-by-step instructions, please refer to the Multi-Zone Leak Detector Application and Panel Manual.

Multi-Zone Leak Detector
Application and Panel Manual
For Leak Detector firmware 5.35F01 and higher

Overview

The Multi-Zone Leak Detector Application and Panel (P/N 851-4074) has a total of six (6) zones. The Visograph display provides a parts per million (PPM) reading. One MRLDS Halo-carbon and CO2 sensor can be connected in each zone. The Multi-Zone Leak Detector application is fully integrated with the E2, has relay outputs for third party devices, or can operate fully independently as a stand-alone device. Leak detector versions 5.32F12 and higher are BACnet MS/TP capable and can be used with E2E 4.09F04 and higher. The BACnet leak detector Description File for E2 is P/N 527-0600.
Each zone is capable of operating an audible and visible alarm based on user defined alarm and spill setpoints. In addition, each zone has the ability to trigger a circuit shutdown in the event of a spill.
The Leak Detector Panel comes equipped with a local strobe and horn. Optional hardware includes remote horn and strobes, MRLDS Halo-carbon and CO2 sensors, and battery backup panel.

1.2 Operation
Each zone will operate a horn and strobe in the event of a leak. If the PPM reading that is sent to the panel has reached the user-configured parameter, the horn and strobe will be activated by a relay output. If a leak is present and it is large enough to reach the spill parameter set by the user, the panel will trigger another set of relay outputs. Through the E2 software or third party system, a spill alarm can trigger a circuit shutdown. In the event that an alarm has been triggered, the user will be able to silence that alarm for a period of time that is user-configurable.
1.3 Panel
The user interface is located on the front panel. From here the user can view status, set parameters, and silence alarms from (in addition to alarm silence buttons located in each zone). Also located on the front panel are power indication lights for the system, each zone, and battery backup status (if an uninterruptible power supply UPS is required).

1.4 Zone Terminal Blocks
Each zone has a dedicated control board to interface field wiring connections with factory wiring connections in the panel. The 538-1125 AC Zone Relay Board and Terminals (for 851-4074 panel only) illustration below shows an example of zone 1 board, terminal strip, and terminal descriptions.

The 851-4550 Leak Detector Panel with DC powered gas detectors has a slightly different leak detector control board than the 851-4074 panel. The 851-4550 panel has a DC control board that is colored red for easy identification from its green AC counterpart in the 851-4074 panel. Additionally, the red 538-1126 DC control board is configured to provide DC power for installations using DC gas detectors. The red 538-1126 DC control board can only be used in the panel designed for it, P/N 851-4550.

2 Set Up Instructions
NOTE: When updating screen parameters on the Visograph, only one Visograph at a time may be connected to the Multi-Zone Leak Detector.
Press the corresponding button along the bottom labeled (T1-T8) to navigate to the desired item. Press SET once to enter edit mode, and use the up and down arrow keys to change values and press SET once to save the selected value.
Main Screen
The main screen shows the associated refrigerated rack system and circuit number of each detector zone, which is listed under the System column. The zone status is shown under the Status column. Active alarms will cause the bell icon to flash in the upper left corner. Press and hold OFF (T8) to silence the alarm located on the panel. The strobe will remain on until the condition no longer exists and the alarm is manually reset. The zones in alarm condition are indicated by flashing AL1 through AL6, respectively. Each zone can be silenced by pressing the corresponding T2 through T7. The zone alarm can be reset by holding the corresponding button for three (3) seconds.
NOTE: Alarm silence and reset functions on the main screen: T2 = AL1, T3 = AL2, T4 = AL3, T5 = AL4, T6 = AL5, T7 = AL5, T8 = OFF
2.1 Configuring Modbus Settings

If the communication to the E2 will be using Modbus protocol, the Modbus address and baud rate must be configured before successful communication will occur.
To set controller information from the Detector Status screen:
1. Press and hold T4 and T5 for three (3) seconds. 2. The Setup screen will appear. 3. Use the up and down arrow keys to highlight and
select Controller Info and press SET. 4. The Controller Info screen will appear. 5. Use the up and down arrow keys to highlight and set
the date, time, and Modbus address. 6. Press SET after each selection to save changes. 7. After all Modbus settings have been configured, a
controller reboot must be performed. Use the down arrow key to select No next to Reboot Controller, press SET to edit and use the arrow keys to select Yes. Press SET again. The controller will reboot and boot back up with the new settings applied.
NOTE: Set the Modbus address to the next available address. Press SET after making each change to save your entries.
2.2 Configuring BACnet Settings
If the communication to the E2 will be using BACnet MS/TP protocol, the BACnet MS/TP settings must be configured before successful communication will occur.
To configure the BACnet Settings from the Detector Status screen:
1. Press and hold T4 and T5 for three (3) seconds. 2. The Setup screen will appear.

5.4.1 Connecting Communication Wires – BACnet MS/TP
The BACnet MS/TP connection should be wired in a daisy chain topology, no star or T configurations are allowed. Connect the BACnet network cable to the three terminal connector on the E2 COM port you wish to assign as BACnet MS/TP. Connect the network cable to the leak detector on the RS485 master port terminals 94, 95, 96.
Reverse the polarity of +/- on the RS485 cable between the E2 serial port and the leak detector serial port. Emerson specs General Cable 92454A (Emerson P/N 135-0600) shielded twisted pair cables for use as BACnet MS/TP wiring.
