and battery voltage. To check the water
contents simply press the test switch to the
water position and the meter will display a
level on the following scale:
Empty -
1
⁄4 -
1
⁄2 -
3
⁄4 - Full
To test battery voltage simply press the test
switch to the battery position, readings
should be taken as follows:
Green region - Fully charged (no charge
necessary)
Yellow region - Adequate charge
(re-charge if desired)
Red region - Low charge (turn on
charger switch to re-charge)
Modules have a water pump running
indicator light.
Cascade/Pump Indicators
This module provides indicators for the
Cascade water heater fitted in your caravan.
The three indicators show the following:
Green LED - Heater is switched on
Red LED - There has been a heater
fault, probably a low gas
supply
Yellow LED - DC voltage supply is too
low for the heater to operate
Also included is a pump running indicator.
This red indicator will light up as a warning
when the water pump has been activated for
either INT or EXT pumps.
SWITCH MODULE
This module contains the control switches
for electrical facilities within the caravan.
Pump switch
This switch merely energises whichever
pump is required (i.e. internal or external).
On the panels there are two indicator lights
to show which pump is running.
Car/Van selector switch
The car/caravan changeover switch provided
in this module should be used in the
following way:
Caravan position
When in this position dc power is available
from the caravan battery to power all 12 volt
electric circuits. If the charger is switched
on, the caravan battery will be charged up
via the charger/transformer unit.
Central position
When in this position with the charger switch
on, power is provided to all 12 volt circuits
via the charger/transformer only. With the
charger off, all dc circuits are isolated. Note:
The switch should be placed in this position
when the van is being towed.
Car position
The switch can be placed in this position
should the caravan battery become
discharged and no mains power is available.
Note: First of all the towing vehicle should be
electrically connected to the caravan via the
12S socket.
Battery/Water test switch
This switch should be pressed to the battery
position to test battery voltage or the water
position to indicate the water remaining in
the inboard tank.
Auto-fill Water System
The system controls the automatic filling of
the internal fresh water tank from an external
pump.
The Auto-fill water system is controlled by
two switches:
1. A start and stop switch sited in the
PMS2000 indicator module.
2. A manual override switch sited on the
control box positioned near the fresh
water tank.
Operation
The process begins when the Start-Stop
switch is briefly pressed at the side marked
‘Start’, thus starting the external pump, the
process can be stopped at any time by
briefly pressing the Start-Stop switch at the
side marked ‘Stop’. The pump will run for
approximately 3 minutes or until the fresh
water tank is full, at which point the External
pump will automatically stop.
Manual Override:- If the Automatic filling is
not required, an override switch has been
included on the Auto-Fill unit, situated near
the internal fresh water tank.
This switch has three positions:-
