7.2.4 Battery
7.2.4.1 Internal verses External Battery Options
The PVS5120 series samplers can be powered via an internal or an external
power supply. The internal power supply is a 7 or 17 Ah, 12 Vdc battery (pn
#
27823 and pn
#
29785) that is mounted in the harness on the top of the control
section of the sampler. This battery can be charged via the charger sold as an
accessory to the sampler (pn
#
27825 or
#
29735). When charging with the
approved charger the sampler can be running and charging at the same time.
Do not try to operate the sampler with only the charger
plugged into ac power. An internal battery needs to be
present to operate with the charger.
External power supply for the sampler must supply 12 Vdc and be connected to
the
Power
connector on the Control Panel via the external power cable that
ships with the sampler. This cable needs to have leads attached that are
compatible with the users external power supply. If using an external power
supply, the user can not charge the external battery via the sampler charger. To
charge an external battery, the user must provide an independent charging
system.
7.2.4.2 VSC100 Battery
7.2.4.3 Fuses
The VSC100 controller contains a 3 Vdc coin cell lithium battery (pn
#
15598)
to maintain user settings and the real-time clock of the sampler during loss of
system power. The battery has an estimated 5 year life under normal operating
conditions/temperatures. The battery is replaceable by the user. See Appendix
, for a tutorial to replace the battery.
Since the controller is a low-power device, this uncovering can be safely done,
taking care that no conductive implement contacts sensitive circuit
components.
Every PVS5120 ships with two fuses. The first fuse is located directly on the
Control Panel of the sampler and varies depending on which pump a user
orders (see TABLE
for more information). The second fuse is a 10 A/32 V
MDL fuse and goes into two yellow caps on the positive line to the battery.
This fuse is independent of pump type.
