9-6. System Diagnostic Screens

Additional system diagnostics are available and accessible through the operator interface. Detail operational parameters can be accessed by pressing

and holding the Run Status

button and pressing the Parameters

kW

V HzA button.

When this feature is initially activated, the following screen appears on the LCD display:

		System Diagnostic Screen
RemCmd: 1023		Off	Cable1: LQD DIAG1
OutI1:	0	A	Cable2: LQD
OutI2:	0	A	ClntFR: 0.75 GPM
IsrcFb:	0	A	ClrSts: Flowing

RemCmd − This is the value of the remote command and the status of the remote contactor.

.Remote controls can be used to enable/disable output. They do not affect output power level.

Out I1 − This is the value of the output current on output 1.

Out I2 − This is the value of the output current on output 2.

Isrc FB − This is the value of the amperage in the current source inverter.

Cable 1 − This is the cable type hooked up to output number one. Possible labels:

SAIR − for an air-cooled cable

SLQD − for a liquid-cooled cable

SPLUG − for a protective plug

SOPEN − no cable or plug in place

Cable 2 − This is the cable type hooked up to output number two. Possible labels:

SAIR − for an air-cooled cable

SLQD − for a liquid-cooled cable

SPLUG − for a protective plug OM-222 166 Page 44
