Page 2: Important Safety Instructions
• To reduce risk of electric shock, de-energize and disconnect the AC input and the battery from the charger before attempting maintenance or cleaning. • Use of an accessory not recommended or sold by SENS may result in a risk of fire, electric shock or personal injury. -

The pots should be covered with either white adhesive paper dots or a hard red varnish. This manual covers installation, operation and troubleshooting of SENS model FC and FCA battery Description and chargers rated at 6 or 10 amps output, 12, 24, 32 and 48 volts. Text, drawing of the housing... - Page 4 FC/FCA Charger Operation & Maintenance – 6 & 10 amp units FIGURE 3.1 FC Charger Mounting (see diagram at end of document for dimensions) 9/32" holes to accommodate 1/4" screws. Level charger on wall if necessary with washers. Use washer, locknut with each screw.
- Page 5 The voltmeter will show battery voltage as soon as the DC connection is completed. Check the voltmeter as soon as the FC connection has been made. If the meter reads zero or is deflecting below zero, reverse the polarity of the battery connections. Do not energize the charger with the battery connected backwards--the DC fuse will blow.
- Page 6 FC/FCA Charger Operation & Maintenance – 6 & 10 amp units that the charger’s rated output power in watts is not exceeded. The charger uses True Voltage Sensing (TVS) to automatically compensate for voltage drop in the charging leads. TVS senses current flow between output current pulses, when current flow and voltage drop are zero.
- Page 7 FC/FCA Charger Operation & Maintenance – 6 & 10 amp units Charge fail: The charger senses voltage rather than current to detect "failure"; once battery voltage drops approximately 1 volt below nominal the alarm activates. This may occur when: a) The battery is fully discharged...
- Page 8 FC/FCA Charger Operation & Maintenance – 6 & 10 amp units NOTE: The charger cannot be correctly adjusted without either a battery or the capacitor mentioned above. This is because SENS’ True Voltage Sensing circuit senses battery voltage only between charging current pulses.

10 to 50 volts. De-energize the charger, disconnect the battery and connect the power supply's output leads to the charger's FC output terminals, being careful to observe correct polarity. Turn on the power supply. Verify on the external meter that polarity is correct. - Page 11 FC/FCA Charger Operation & Maintenance – 6 & 10 amp units Symptom Possible cause Test Repair procedure No output AC or DC fuse blown Replace fuse Battery not connected Connect battery No AC power Restore AC Ammeter disconnected Reconnect TB-3 disconnected...
