Code 2028: “LPS mains voltage too high” (Error)
Situation Solution
The mains voltage applied to the
input pins of the LP S m odule is
above specs.
Switch O FF the pr ojector imme diately!
Apply a v oltage within spec s to the mains input sock et of the projector. The maximum
input voltage is 240V AC, the minimum input voltage is 2 00V AC . (reference 1 image 5-6)
Code 2029: “LPS requested output power too high with low mains voltage” (Error)
Situation Solution
The requested power for the lamp
can not be delivered by the LPS
modules because the mains v oltage
is too low.
Apply a v oltage within spec s to the mains input sock et of the projector. The maximum
input voltage is 240V AC, th e minimum input voltage is 200V AC.
Code 2030: “LPS internal voltage error” (Error)
Situation Solution
Malfunction power circuitry inside
the LPS module.
Replace one or both LP S modules. See "Lamp Power Su pply", pa ge 169.
Code 2031: “LPS internal error” (Error)
Situation Solution
Mains input disconnected from one
of the LPS power input pins.
Check if the wire units (reference 1 , 2 & 3 image 5-1) of
the m ains voltage are connected
with the power input pins of the LPS module. Check both LP S units.
Malfunction of one of the LPS
modules
Replace one or both LP S modules. See "Lamp Power Su pply", pa ge 169.
Malfunction LPS r elay. (reference 4
image 5-2)
Check the functionality of the L PS relay. Replace if needed. See XXXXX .
Code 2032: “LPS failure fan 1” (Error)
Situation Solution
One of the two LPS fans fails.
Possible reasons: bad fan, not
connected, fan tachometer not
working, etc.
If this failure was detected during
the startup of the LPS module then
the lamp can not be ignited. If this
failure occurs during an event then
the event can continue until the lamp
is switched off.
Replace one or both LP S modules. See "Lamp Pow
er Su pply", pa ge 169.
