Page 7: Chapter 2│ Description
2. Surveyor 4B is Class II equipment. Surveyor 4B is equipped with a small "NORMAL" box (58 x 105 x 90 mm). It can be snap-fastened onto a standard symmetrical DIN rail and should imperatively be integrated in a closed electrical equipment cabinet. - Page 8 The components used in operation are located on the front of the appliance: adjustments and tests on the top (Item 1, Figure 1), indicator lights on the FRONT face (Item 2,Figure 1), connections at the bottom (Item 3, Figure 1).

Page 9: Chapter 3│ Mounting Of The Surveyor 4B
Chapter 3│ Mounting of the SURVEYOR 4B The surveyor 4B appliance fitted on its symmetrical DIN rail must be installed in a closed electrical equipment cabinet. A space of 100 mm is necessary around of the Surveyor 4B. The Surveyor 4B should preferably be located in a monitored location (such as a guardhouse, control room or instrumentation room). - Page 10 Surveyor 4B User Manual...

. The nature of the current and line voltage must be checked. The line voltage must match the voltage specified on the plate fitted on the Surveyor 4B. The voltage is configured in the factory. -
Page 12: Dc Power Supply
The 12 volt power supply can be connected to the points marked 0 and 12 V on the Surveyor 4B terminal block (see Figure 2, Item2). The Surveyor 4B must be protected on the upstream side by a fuse (630mA) with time-delay. -

Chapter 5│ Operating instructions Switching on It is assumed that all the necessary connections have been made and that the whole installation complies with the standards currently in force. As soon as the SV 4B is supplied with power, it is ready to use and the GREEN light-emitting diode lights up (rep 1, Figure 7). - Page 18 (humidity, temperature, dust, etc.); however, it must not exceed one year. The general manager should put safety procedures in place on-site. OLDHAM cannot be held responsible for their enforcement. Surveyor 4B...
- Page 19 Adjusting the "gas alarm" thresholds Using a "reference gas kit" (gas cylinder + pressure regulator, etc.), inject the reference gas with a content level higher than the first threshold desired. (For example, threshold 1 will be 20% LEL, so a minimum of 25% LEL should be injected).
- Page 20 (or to below the threshold). This is done by pressing the Ack. key (item 5, Figure 8). Automatic mode: When a gas alarm is triggered, it is cleared automatically as soon as the content level falls below the alarm threshold. Surveyor 4B User Manual...
