MacKay Guardian™ Solo
Operation and Maintenance Guide, v. 1.5
9. Maintenance and Repair
This section deals with: testing a new battery pack, replacing meter battery packs on-street, in-
shop repairs, replacing a coin chute and card readers, testing a reassembled meter, annual,
monthly and weekly maintenance, handling, storage and transportation of meters and how to
read and interpret the meter status message of the
MacKay Guardian™ Solo.
9.1 Testing a New Battery Pack
1)
Using a digital multi-meter (DMM) set to the proper voltage range (10V DC) test the
terminal voltage of the new alkaline battery pack. Insert the positive and negative leads
of the multi-meter into the battery connector. A fresh unused alkaline battery pack has a
measured voltage of 9.0V DC or higher.
2)
The Solo will signal a low battery condition when the battery pack voltage is at
approximately TBD volts DC. It is recommended that a battery pack be considered at or
near its “low battery” threshold, and should not be used, if it has a measured, unloaded
(open terminal) battery voltage of approximately TBD volts or below.
9.2 Replacing Meter Battery Packs
To replace the battery pack on a meter that has indicated that it is in a low battery condition (If the
display is not blank, i.e. showing time/out of order/zeros) or the battery pack installation date is
more than 12 months old, do the following:
Note: Avoid replacing the battery pack when it is active (i.e. during a reset sequence).
1)
Unlock and swing open the Solo top cover from the back cover. There is no need to
remove the meter from the housing during Solo battery changes.
2)
Unplug the battery harness from the main board by first gently squeezing the connector
interlock tab and then lifting up on the connector. The battery harness cable /connector
should pull clear of the main controller board connector.
3)
Remove the Solo battery pack.
