- 8. Maintenance If used correctly, the instrument does not require any particular maintenance. The only maintenance of the ALMO 6 consists of frequent cleaning of all surfaces from dust and other deposits.
8.1. Accumulator (rechargeable batteries)
In order to check functioning of the rechargeable batteries, monitors with UPS (optional) should be disconnected from the mains once a month for one hour in order to operate with the batteries.
If the rechargeable batteries are unable to last for this time period, they have to be replaced.
In case of (rechargeable) battery operation, a battery symbol is displayed in the lowest line on the display. If the voltage is too low, it is indicated as selected in the menu under 'Error displaylUndervoltage' (see 4.9.5). The instrument is turned off automatically if the voltage is too low.
After max. 2 years, the rechargeable batteries (type AA) have to be replaced by new ones.
Attention! Never use non-rechargeable batteries. The monitor can be destroyed by leaking or boiling batteries.
In case of stocking the instrument for a long time, the rechargeable batteries have to be removed in order to avoid total discharge.

- Flashlight with sound Dimensions 0 90 mnn, height 80 mm
- Flashlight without sound Dimensions 0 100 mm, height 80 mm Cable to connect the alarm units The length of the connection cable for flashlight and signal towers is manufactured according to customer specifications.
Adapter for network solutions The order, the number of individual devices and the interface types can be mixed as needed. The maximum number of devices (including ALMO 3/6) is 16 and up to 48 probes will be supported.
No adapter is needed to transmit the data via USB and RS-232. However, the maximum length of each RS-232 connection is lOim and that of the USB connection 5m.
The length of the USB connection can be increased by connecting USB repeaters or USB hubs.
- Adapter RS-232 to RS-485 and distributor Since each ALMO has only one interface connect the RS-485 cable must be wired in external cases. The interface is then set to RS-485 (see 4.9.4). The distributor must be in the vicinity of the respective ALMO. The total length of the RS-485 connections should not exceed 500m.
- Adapter RS-232 to RS-422 w Il !* I No external adapters are needed when using a 5 multiple RS-422 card in the PC. In this case, the ____
interface is set to RS-422 (see 4.9.4). The length of the RS-422 connections may be 500m each.

ATTACHMENT 1 ALMO 6 Operating Manual Additional Display ALMO AD 1 The device ALMO AD 1 can be connected as an addition display to an ALMO 6 or ALMO 3. Several ALMO AD 1 can be connected in series. The measured data are supplied by ALMO 6 or ALMO 3. The alarm thresholds are defined in ALMO 6 or ALMO 3.
The setting for the device configuration and alarm assignment for exceeding of the alarm threshold or malfunctions takes place on the menu level. Visual and acoustic warnings are enabled when alarm thresholds are exceeded or if a malfunction occurs. Measuring electronics and display unit are integrated in a plastic housing.
A large LC display is incorporated into the front panel of the housing. The value currently measured by the connected detector is displayed on this LC display.
Additional Probe Display ALMO ZSA The ALMO ZSA system, in connection with the ALMO 6, allows you to display the local dose rate of up to 6 detectors, for example, Geiger-Muiller or Nal detectors. The ALMO ZSA is an additional display unit for the probe measurement values. The ALMO 6 sends the probe data via an interface. Several ALMO ZSA can be operated in connection with the ALMO 6.
Two freely definable alarm thresholds can be defined in the ALMO 6 for each probe. This setting is done on the menu level of the ALMO 6. A visual / acoustic alarm is triggered whenever an alarm threshold is exceeded.
Optionally the device can be equipped with an emergency power supply.
Depending on the connected components (LED traffic light), the ALMO ZSA will continue to work for up to 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> after power failure.

Types of Adsorption There are three types of adsorption that concern us: 1. Kinetic, 2. Isotopic Exchange, and 3. Complexing or Chemisorption.
Carbon 3ampler Blank Off Plug and Canister/PlugRemoval Tool (furnished) Kinetic: Kinetic adsorption of a gas molecule or chemical vapor is the physical attraction of the molecule to the carbon granule by electrostatic forces. These forces, as they apply to small particles, are governed by van der Waals theories, and these attraction forces are termed van der Waals forces. Since these forces are physical in nature, the forces can be undone by physical effort. Thus, high temperature, high humidity, or other natural causes may cause an adsorbed contaminant to desorb.
Generally, the higher the boiling point, the larger the molecule size, and the lower the melting temperature, the easier the molecule is to kinetically adsorb and the stronger it is held once it is adsorbed.
Isotopic Exchange: A second "adsorption" mechanism is isotopic exchange. Radioactive materials usually have a family of isotopes. If a stable isotope is adsorbed on the carbon initially, an unstable isotopic compound will, when it comes into contact with the stable form of the element, exchange the isotopes. The 19

Methyl iodide efficiency, structure of the impregnant. An example of this for example, is determined by challenging the is carbon impregnated with K13. The radioactive carbon with an actual radioactive methyl iodide form of iodine in the organic form CH 31131 will vapor. The amount of the contaminant upstream isotopically exchange with the iodine on the of the carbon is known, and the amount that is carbon. This exchange is nondirectional, collected on backup beds is measured. The meaning the adsorbed (exchanged) radioactive efficiency of that carbon sample to remove species of iodine may very well exchange methyl iodide is easily calculated by comparing again. The result will be a different airborne the counts of the carbon sample to the counts radioactive methyl iodide molecule. This new on the backup beds. Test parameters such as radioactive molecule may again isotopically temperature and relative humidity greatly affect exchange with stable iodides on the carbon the efficiency.

The installed system Complexing or Chemisorption: A third is subjected to a test gas that is easily adsorbed, capture mechanism is chemisorption. This is such as R-1 1 (trichlorofluoromethane). The the actual complexing, attaching chemically, of penetration, or by-pass of the R-11, is measured a radioactive iodine species to a stable downstream of the filter and that amount is impregnant that has the ability to share compared to the amount measured upstream electrons. Once the iodine is complexed, it does of the filter. A penetration value in percent is NOT desorb similarly to isotopic exchange. easily calculated from the collected data. This However, it may desorb similarly to the kinetic is also termed mechanical efficiency.
adsorption discussed. But if it does, the entire impregnant desorbs from the carbon, not just the iodine. An example of this is to impregnate the carbon with triethylenediamine (TEDA) or some other tertiary amine.
To take advantage of both impregnants and capture mechanisms, carbon can be co-impregnated. This allows the carbon to be used as a kinetic adsorber, an isotopic exchange medium and a complexing agent.
As long as the operating conditions are kept within normal bounds, the carbon will perform Residence Time as required. It will perform under high humidity Residence time is the term given to the time that conditions and under high temperature a gas stream contacts a carbon bed. For conditions better than a carbon with a single example, if a carbon bed were a foot thick and impregnant. the air stream moved at one foot per minute, Efficiency vs. Penetration the residence time would be one minute. Itwould take one minute for the air to move through the There is often confusion between "efficiency" bed.

Where:
RT = 0.125 second RT = Residence time (seconds)
D = Depth of carbon bed (inches)
The concept of residence time is very important V = Velocity of gas through bed (feet/min) from the designer's point of view. That is why Most of the time, the velocity will not be given Flanders/CSC is taking a lot of time to explain it and must be calculated from the relationship: fully.

As the gas Q =Quantity of gas flowing through bed enters the bed, it must have time to interact with (CFM) the impregnants on the carbon.

- 1. HEPA filters should be used to trap dangerous particulates and protect the carbon filters from collecting particulates and thereby increasing the adsorber's pressure drop.
