How to Use This Manual Thank you for investing in Copeland’s Multi-Zone Gas Monitor. To assure operator safety and the proper use of the monitor, please read this manual. It provides important information on the installation, operation, maintenance, and servicing of the monitor and display module.This manual provides important information on how to install, operate, and service the RLDS.
The protection provided by the monitor may be impaired if the following hazard symbols and/or associated words are the monitor is used in a manner not specified by Copeland. defined as follows. Modifications to this monitor, not expressly approved, will 1.4.1 Warning...
Recommended monitoring levels based on compliance to cause of the fault. All 800# models of the RLDS come with the ANSI/BSR ASHRAE 15-2007 and ASHRAE Safety Code 34- number of line-end filters (plus one extra) to match the 2007 have been developed and are listed in Appendix A: number of zones for each model.
Response to the Presence of Multiple Refrigerants The RLDS is a refrigerant level monitor, not a gas analyzer. You must program the monitor to test for a specific refrigerant in each zone, and it will only return accurate concentration readings for that particular refrigerant. If a leak occurs of another refrigerant gas type, the monitor may return incorrect readings.

WARNING Shock hazard! Always disconnect the AC power before working inside the equipment. Drilling holes in the RLDS enclosure may damage the unit and will void the warranty. Please use the CAUTION knockouts provided for electrical connections.
Dirt, grease, and oils can adversely affect the operation of the RLDS. The monitor should be installed out of direct sunlight in a clean, dry area that is not subject to temperature or humidity extremes.
3.2.1 Overview Individual sample lines are run from the RLDS to each area of the facility to be monitored. Additionally, a purge line is installed to provide clean air for resetting the infrared zero baseline. An exhaust line is installed to vent residual gas away from the monitor.
If this is not possible, an optional charcoal filter assembly (P/N) can be used with the RLDS to filter refrigerant from the purge line. It may be mounted adjacent to the monitor. A line-end filter (P/N) should be attached to the end of the purge line when the charcoal filter is not used.
RLDS is used in wet locations such as meat preparation rooms. When water is pulled into the system, a System Fault will occur, closing the fault relay located at the bottom of the main control board. To turn power off to the RLDS when this occurs, wire the fault relay into a spare 16AI input.
RLDS Electrical Wiring The RLDS uses a universal power supply that is capable of accepting inputs of 100 to 240 VAC, 50/60 Hz. The monitor's power consumption is 20 Watts. It is highly recommended that the monitor be connected directly to the AC power source, preferably on its own circuit.
Drilling holes in the RLDS enclosure may damage the unit and will void the warranty. Only use WARNING the knockouts provided for electrical connections.

Connecting to a Building management System The RLDS may be connected to a Building Management System via the RS-485 connector. The node address on each RLDS may be set from 1 to 15 in order to identify itself to the Building Management System.
After both are operational, connect the RS-232 cable and start the software program. Apply power to RLDS monitor and allow it to warm up. Note that on CO2 models, a “Clearing Purge Line” message is displayed for approximately 2.5 minutes before warm up begins.

Overview The RLDS includes four SPDT relays whose contacts are rated 2 A at 250 VAC (inductive) and 5 A at 250 VAC (resistive). These relays are used for the connection of external alarm devices that are activated when the relay is energized. The relays are factory...

Use the UP/DOWN cursor key to modify the Digipot value. 6.21 Node Address Each RLDS on the network must have a distinct node address. The node address may be set from 1 to 64. Press the ENTER key to adjust the setting.
Normally each RLDS will perform measurements on its active zones sequentially and without user input. The total time it takes an RLDS to complete a measurement cycle is directly proportional to the number of active zones and the physical length of the air lines.
7.2.6 Log Interval 7.3.2 Spill Level The RLDS retains a data log of 100 measurements for each This is the concentration level in PPM that will activate a spill zone. The log interval is the number of minutes from 1 to 1440 alarm condition.
SETUP - using the right arrow key, navigate to the Zone Setup screen 1 (Figure 7-1). This enables review of the zone setup parameters and accesses the Trend screen. Use the ESC button on the RLDS unit to go back to the previous menu. Figure 7-3 - Alarm Summary Screen The Alarm Summary screen displays a list of all alarm conditions pending across the network.
Repeat this procedure to acknowledge any remaining alarms Once all the alarms associated with a given RLDS are acknowledged, its red LED will turn off, and any external alarms connected to the RLDS relays will deactivate.
NO FLOW message in each individual zone affected. Check for a blockage in the air sample line or at the line-end filter. Once the blockage has been cleared, the RLDS will return to normal operation after the zone has been sampled.
Once the system malfunction has been corrected, it may take some time for the fault condition to clear completely. If the fault is associated with a specific zone, the RLDS must first cycle back to the affected zone before it returns to normal operation. At that time the yellow LED will turn off and any external alarms connected to the monitor's alarm relays will also turn off.
FACTOR to 1.000. Next, set up the RLDS for a logging interval of zero minutes (Section 7.2.6, Log Interval), and place the RLDS in its zone hold mode for the zone you wish to use for calibration purposes (Section 6.13, Re-Zero Mode).

RLDS alarm will be created. In order for the alarm to be removed the MODBUS master will write a “0” to the ALARM parameter in the ZONE register. This will cause the alarm to be “silenced” in the RLDS (i.e., the alarm relays will return to their normal state and the ALARM lamp will be extinguished).

See description of STATUS REGISTER RLDS Hold Mode The RLDS can be made to hold or “dwell” on a particular zone if necessary. The length of the hold time is defined by the HOLD TIME parameter in the System Data Register.

RLDS Service Mode The RLDS can be placed into service mode if necessary. During service mode the unit will take no measurements, any and all alarms are silenced, and all relays are opened. The unit automatically comes out of service mode after a preset interval defined by the service_mode_TO parameter in the System Data Register.
