Overview
The iPro Refrigerant Leak Detector (P/N 818-8003) is a device that provides an alarm status at different parts per million (PPM) levels using the Emerson MRLDS leak detector (1-5V version P/N 809-1001), and a graphical display. For each analog input, configurable as 1-5V or 0-10V, the controller will be set up to activate a relay to alert of an advisory situation. The analog inputs can be configured within Min and Max PPM range (0-1000 PPM default for MRLDS).
When Relay 1 is activated (ON), the relay defined for the horn/light (RHOR) will be ON. If the digital input (DIHL) is pushed for 2 seconds, the RHOR relay will be switched off. If after the DTBR time the alarm situation is still active, the RHOR will be activated again. The horn can also be reset on the visograph status screen by pressing OFF. For Relay 1, the polarity can be defined as open or closed, and the delays can also be defined as ON or OFF. The relay defined as RHOR has to be set up without any ON or OFF delay (if the user will define a value, the system will automatically consider it as “0” (zero).
1.1. Application Operation The leak detector application is split in 3 different alarm setpoints. Depending on the PPM level read in the leak detector, these 3 setpoints are defined as: • Notice • Alarm • Spill The relay output can be linked with Analog Input 1. By default, Analog Input 1 will be linked to Relay 1. (It is not possible to have the same relay linked to multiple analog inputs.) The relay output can be set up as either a Notice, Alarm, or Spill to trigger the advisory and is user-configurable. The advisory setpoints have a Hysteresis, for example: • Analog Input 1 • The PPM setpoints for Notice, Alarm, and Spill • Relay 1 linked with the Analog Input 1 Then Relay 1 can be assigned with the following options: • Notice: The relay is ON when the leak detector is above this setpoint • Alarm: The relay is ON when the leak detector is above this setpoint • Spill: The relay is ON when the leak detector is above this setpoint

3.1. Visograph Steps
The Controller Information screen gives you access to date and time configurations and other updates. The main screen shows the time/date and summary of the input. Active alarms will cause the bell icon to flash. Press and hold OFF to stop the alarm.
Press the up and down arrows to scroll through the options on the current visograph screen being viewed. Press the left and right arrows to page through the visograph screens.

Figure 3-7 - Configure Parameter Screen 3
Disable or enable Analog Input 1 from this screen. Press SET to scroll through the options, press SET again to configure and press SET again to save the value.
Set the PPM trigger types for Analog Input 1. PPMn1 is a notice value, PPMa1 is an alarm value, and PPMs1 is a spill value.

ATA1 is the alarm type active for Analog Input 1. LOR is the light output relay setting (the main alarm output. DIHL is the physical digital input setup and can be set to alarm, spill, or notice. DTBR is the delay for the horn. Once the horn is silenced, and the alarm is still active, DTBR is the amount of time that will elapse before the alarm will turn on again. ROD1 is the on delay for Relay 1.
Set the off delay for Relays 7 and 8 (RFD7; RFD8), and the polarity for Relay 1 (RLP1).

From this screen, configure the digital output polarity for Relay 7 and 8 (RLP7; RLP8), and the digital input polarity (DIP1) for Relay 1. Figure 3-10 - Configure Parameter Screen 6
Set the on delay for Relays 7and 8 (ROD7; ROD8), and the off delay for Relay 1 (RFD1) on this screen.

Wiring
Figure 4-1 - Wiring Layout
NOTE: Check the wiring of the horn and strobe. Each needs to be controlled by its own relay/iPro output so that the horn can be silenced while the light remains on.
WARNING! All power must be shut off prior to wiring, installation or service. More than one disconnect may be required to de-energize this panel
WARNING! Tighten all connections to recommended specifications before applying power. Use recommended field conductor wire sizes. Copper conductors only, 60°C (140°F) minimum. Recommended Specifications: Torque: 0.5 Nm Wire Sizes: 22-10 QWG
