Vapor Pressure Sensor Select <br /> The Vapor Pressure Sensor(VPS) Select is located under the 4-20mA module setup. This is where we define the input <br /> channel and select the VPS. Go to the 4-20mA Module setup and make the following changes. If Electronic Line Leak <br /> detection is being installed, some channels will be used for the LLD transducers. <br /> Group Name Parameter Name Parameter Value Explanation <br /> 4-20mA Input Modules <br /> Module# Channels (n) Select"1"for the Vapor Pressure Sensor <br /> Channel# Name Ex. ISD Pressure Sensor Unique name for VPS <br /> Enabled Yes Keep as"Yes" <br /> Service Type Vapor Recovery Monitor Select correct service type for application <br /> Remote ATG Serial Port Settings <br /> If the Console will be getting ullage volume from a Remote ATG then the serial port must match that of the other tank gauge. <br /> Group Name Parameter Name Parameter Value Explanation <br /> Power Supply Module <br /> COMM 2 Baud Rate 9600 Set to match External ATG <br /> Data Bits 8 Set to match External ATG <br /> Parity None Set to match External ATG <br /> Stop Bits 1 Set to match External ATG <br /> Response Timeout 8 Leave as default <br /> Relay Mapping <br /> Relay mapping is necessary for proper shutdown of dispensers. The programming of the Relay Module will tell the VRM <br /> which Vapor Flow Meter will control which Dispenser.As you will see this is why we enter a unique name for each Flow <br /> Meter so we can easily identify the channel. <br /> Note: By mapping the relay to the VFM in the following setup, we now enable the VRM to automatically shutdown dis- <br /> pensing upon ISD alarms. <br /> Group Name Parameter Name Parameter Value Explanation <br /> Relay Module <br /> Module# Channels (n) Select number of dispensers <br /> Channel# Name Dispenser 1 Power Unique name for relay's purpose <br /> Enabled Yes set to"Yes" <br /> Type Dispenser <br /> Polarity Normal Set to Normal <br /> Logic OR Logic Set to OR <br /> Physically Wired As Normally Closed Set to Normally Closed <br /> Number of Inputs 1 Set to 1 <br /> Input 1 Type Probe Module Select Probe Module <br /> Channel VFM Disp 1 Select the VFM associated with this Dispenser <br /> Additional relays may be used for other purposes such as submersible pump control or external alarms.
