Test Lamp
The Test Lamp is a battery operated, rechargeable, test source specifically designed to test General Monitors’ IR Flame Detection Systems. It consists of a high-energy broadband radiation source that emits sufficient energy in the infrared spectra to activate the IR detector. To simulate a fire, the TL105 Test Lamp automatically flashes a signal that the FL5000 recognizes. The lamp must be set to rotary switch position “4” to be recognized by the FL5000.
Operating Instructions
| • | The FL5000 has the ability to be put into a special test mode activated state by momentarily grounding the test mode pin on the unit or by issuing a Modbus write command to register 0x4A. |
| • | The unit will respond by going into this test mode activated state and by blinking a unique flashing pattern with the green LED on for 0.9 seconds and off for 0.1 seconds. The analog current output will respond by outputting 1.5 mA (3.5 mA with HART and small HART current disabled). |
| • | While the FL5000 is activated in test mode via the Test Lamp, the FL5000 will detect the TL105 Test Lamp as a flame source. |
| ○ | The analog output and relays will respond as if a flame were present. |
| ○ | The analog output will rise from 1.5 mA (3.5 mA with HART and small HART current disabled) to 16 mA (warning condition) and then to 20 mA (alarm). |
| ○ | Relays will trip. |
| ○ | In addition, an alternating red/green LED blink pattern is displayed. |
| • | By momentarily grounding the test mode pin a second time, or by re-issuing a Modbus write command to register 0x4A, or after a 3-minute time out, the unit will return to normal operation in the Ready state. |
| • | The TL105 Test Lamp triggers the FL5000 into test mode, causing an alarm condition. |
It is important to begin a series of flame detector checks with a fully charged Test Lamp. Stand between 10 and 35 feet from the FL5000 that is to be tested and aim the Test Lamp directly into the detector window. Press the ON button and be sure the high intensity pulsing beam strikes the detector face squarely. Hold the Test Lamp as steady as possible.
To conserve charge, do not operate the Test Lamp longer than is necessary to test each channel.
When the battery level drops below the level required to maintain the proper intensity of the lamp, an internal low voltage circuit will shut the lamp off until the battery has been recharged. Please refer to the TL105 Test Lamp manual for complete operating instructions.
Recharging Instructions
Insert the charging plug into the receptacle. Complete recharging takes 3.5 hours minimum.
NOTE: Charging must be carried out in a non-hazardous area. The charging receptacle is located inside the housing adjacent to the ON button. To gain access, it is necessary to unscrew the knurled plug from the body of the unit. The plug is secured to the ON button by a safety strap to keep it from being lost. Replace the plug after charging is complete.
It is recommended that the Test Lamp be kept on charge when not in use to prevent excessive battery discharge. The batteries may be charged an average of 500 times before the battery pack must be replaced.
