On VP 2000 slide processors or heating modules with serial
numbers 32000 or greater, the following additional LED states
may be observed, representing two fault conditions of the
heating module:
Table 5.2:
Status LED Fault Conditions for Select Models
(Serial number 32000 and higher)
Flashing
The LED will have a steady flash rate
(approximately 1 second ON and 1 second
OFF) when the basin is being heated up to its
programmed set-point temperature. When
the basin temperature reaches 2°C below the
set-point temperature, the LED will change to
Steady ON, indicating that the control system
is now maintaining temperature within the
programmed temperature range.
LED State Description
Rapid
flashing
If a basin heater is stuck on when it should be
turned off, the LED will have a rapid flash rate
(approximately ¾ of a second ON and a ¼
second OFF). If this occurs, the VP 2000
processor should be immediately powered
down and a Field Service Representative
contacted for assistance.
Slow
flashing
If a fault with the basin temperature sensor is
detected, the LED will have a slow flash rate
(approximately 2 seconds ON and 4 seconds
OFF). If this occurs, the basin heater will be
turned off automatically. If slow flashing is
observed, the VP2000 processor should be
powered down and a Field Service
Representative should be contacted for
assistance.
