| SERIES HSP SIGNALS AND FLAGS | |||
| Specification | Rating/Description | Condition | |
|
Status Flags (Form C dry relay contacts) (1) |
POWER: | Indicates low source voltage; signal asserted 5msec prior to loss of output voltage. | Both NO and NC contacts available. |
| OUTPUT: | Indicates normal operation | ||
| OVERTEMP: | Overtemperature shutdown | ||
| FAN FAIL: | Failure of internal fan | ||
|
Status Indicators, front panel LEDs (1) |
POWER: | Green | Lit when a-c is sufficient. |
| DC FAIL: | Red | Lit when output failure is detected. | |
| OVER TEMP: | Yellow | Lit when thermostat operates. | |
| FAN FAIL: | Red | Lit when fan failure is detected. | |
|
Test Point, Setpoint Monitor |
Voltage: | 0.1 x EOUT | |
| Current: | 0 - 5V full scale | ||
|
Auxiliary Voltage (isolated) |
4.5 - 5.5V d-c isolated 0 - 100 milliamperes |
Present whenever housekeeping supply is operating. | |
| (1) | Status indicators and status flags are isolated and operate independently although driven by the same detector circuit. |
