For PCR:
• Open the top access cover and locate electrical panelinside.
• See Layout A at the end of this section to locate the UV
ballast, relay board, and connector B inside electrical panel.
• Turn on the cabinet by connecting to the main supply, then
switch on the UV by pressing UV button on
membrane/keypad. Make sure that the front cover is
attached and the LCD displays UV mode.
• Check AC voltage at UV ballast input (between pin NO on
J15 terminal on relay board to neutral), see Figure 9-4.
• It should be 230 VAC ± 10% for 230 V cabinets or 115 VAC ±
10% for 115 V cabinets.
• If not, check the LS8 relay and F8 fuse (refer to possible
cause 6 below)
For SCR:
• Open the top access cover and locate electrical panelinside.
• See Layout B at the end of this section to locate the UV
ballast and connector B inside electrical panel.
• Turnon the cabinetby connectingto the main supply, then
switch on the UV by turning UV timeron. Make sure that
the front cover is attached so that the unit is in UV mode
operation.
• Check AC voltage at UV ballast input (between pin
connector A-6 to neutral terminal block).
• It should be 230 VAC ± 10% for 230V cabinets or 115 VAC ±
10% for 115V cabinets.
• If not, check the UV timer, relays K1, K2, and K3 wiring
connections. Verify that the building voltage is also correct
and not fluctuating.
For PCR/SCR:
• Disconnect male connector B on electricalpanel.
• Turn on the unit by connecting to the main supply.
• Turnon the UV, then check AC voltageat ballast output
(between female connector B pin 3 and 9[for PCR], pin 7
and 8[for SCR]). It should be around 10-25 VAC for 230V
cabinets or around 450-600 VAC for 115 V cabinets. See
Table 6 below.
