2150EX Area Velocity Flow System Section 5 Maintenance 2. Align the connectors and insert the new battery pack into the Battery Module. 3. Check the humidity indicator disk inside the door. (See section 5.4.2.) 4. Replace the door. Align the small triangle on the door with the triangle above the battery port, push inward, and rotate 1 /4 turn clockwise so the curved arrow is at the top of the door. Repeat steps 1 through 4 to install the second battery pack. When finished, reconnect the 2150EX module(s). Note The battery packs should always be replaced as a pair. Never mix old and new batteries. Battery packs should be disposed of according to local battery disposal regulations. Note For storage, the battery packs may be rotated 180 degrees and inserted into the 2191EX. This disconnects the packs for storage. 5.3.2 SLA2191EX Lead-Acid Batteries The lead-acid battery packs should give you several weeks of service before they need recharged, depending upon your data storage intervals (see Table 1-5 and Figure 5-2). Figure 5-2 SLA2191EX Battery Pack Voltage Chart 5-4
2150EX Area Velocity Flow System Section 5 Maintenance Measuring Input Voltage Input voltage can be monitored while you are connected to the 2150EX with Flowlink. The 2150EX also can record input voltage readings. The Flowlink voltage readings will drop lower when the batteries are nearly depleted. The chart in Figure 5-2 shows the noticeable voltage drop that starts to occur when the battery pack begins to discharge. Keep in mind that battery discharge rates vary widely depending on the your system’s operating environment. Input voltage can also be checked manually by disconnecting the 2150EX module(s) from the 2191EX battery module and attaching the volt meter to the connector on top of the 2191EX. Check the battery packs individually, not as a pair. WARNING When using the above method to check voltage, use care not to short any pins. CAUTION Do not deep discharge the SLA2191EX battery packs, or you will reduce their cycle life. Battery life is improved by regularly scheduled recharging before a drop in voltage is indicated. Charging Batteries Charge the batteries only with Isco’s 8V2191SLA Lead-Acid Battery Charger, P/N 60-2004-343 (Figure 5-3). The maximum ambient temperature when charging is 50°C or 122°F. Never charge the battery packs in a hazardous atmosphere! WARNING Charge SLA2191EX battery packs only with the 8V2191SLA charger at an ambient temperature below 50°C (122°F), and never in a potentially explosive atmosphere. CAUTION Due to the self-discharge characteristics of this type of battery, it is imperative that the batteries be charged after 6 to 9 months of storage to avoid possible permanent loss of capacity due to sulfation. 5-5
