Safety Information  Connecting Utilities CAUTION: To  ensure  the  safe  and  efficient  operation  of  the equipment  and  adherence  to  existing  laws  and regulations,  only  qualified  personnel  should  make utility  connections.  Pall  Corporation  requires  that certified  electricians  complete  all  wiring  connections and  that  qualified  personnel,  working  with  Pall Technology  Services  representatives  if  possible, complete all plumbing work.  Pall Corporation is not responsible  for  and  equipment  warranties  may  be voided from any damage or personal injury caused by unqualified  personnel  performing  utility  connections and/or installations!   1.2. Pall System Components  Pall Corporation is supplying a system comprised of WiFi Gateways, Filter Nodes, and Fluid Interfaces to monitor the health of the hydraulic fluid within the system.  Filter Nodes and Fluid Interfaces monitor the state of the fluid directly through attached sensors, and report wirelessly to the Wi-Fi Gateway.  The Gateway then relays the system state through the cloud to the backend application which monitors and controls the Filter Node and Fluid Interface operation.  All external sensors along with associated cables for connecting the sensors to Filter Nodes and Fluid Interfaces are supplied as part of the system.  Power supplies and associated cables are not supplied as part of the system and are the responsibility of the customer.

Installation & Setup 2.1. Filter Node Installation 2.2. Providing a WiFi Access Point The customer site must provide a WiFi access point (2.4 GHz Wi-Fi 802.11 a/b/g/n) that is in range of the gateway.   If a WiFi access point is not available, but a wired/Ethernet connection is available at the customer’s site, Pall recommends one of Cisco’s Meraki wireless LANs, such as the MR18 (https://meraki.cisco.com/products/wireless/mr18) indoor access point.
 18 Athalon®CM & Crixus™ User Manual   If a WiFi access point is not available and a wired/ethernet  internet  connection  is  not available,  Pall  recommends  one  of CradlePoint’s  wireless  routers,  such  as  the MBR1200B  wireless  router  with  3G/4G wireless  WAN  connectivity (https://cradlepoint.com/products/mbr1200b).  Wireless routers connect with the internet via mobile  broadband  service  available  from carriers in the customer’s region.  A wireless router  provides  a  WiFi  access  point  for  the Prodigy Gateway.       2.3. Configuring the Athalon®CM Gateway The customer must configure the WiFi Gateway to communicate with  an on-site WiFi access point.  The gateway associates to a WiFi access point using a service set identifier (SSID) broadcast by the WiFi access point.  The gateway securely communicates with the following common WiFi security types:  Open (no security code), WEP-40, WEP-104, WPA (AES & TKIP), WPA2 (AES, TKIP & Mixed mode).  Each gateway comes with a unique MAC address assigned by the factory, which may also be used for authentication.  Upon initial power-up, the WiFi Gateway will function as a WiFi Access Point.  Using a laptop or similar device, connect to the gateway’s network SSID, which is set to its MAC address.  Once connected, browse to the Configuration page at 192.168.10.1:7000/Config.  On the Configuration page, fill in the SSID, Password, and Security Mode of the WiFi Access Point the gateway should communicate with, and press the “Submit” button (See Figure below).  The settings will be saved in the gateway.  Once configuration is complete, press the button on the gateway enclosure to switch the gateway from Access Point mode to Client mode.  The Prodigy gateway will now communicate with the cloud based server through the WiFi access point.  If the WiFi Access Point needs to be changed in the future, the Prodigy gateway can be placed back into its WiFi Access Point mode by pressing the button on the gateway enclosure. 7. Operation 8.
