Hazard and Safety Information
This manual uses the following standard safety protocols:
WARNING
CAUTION
NOTE
The Service Pendant has no user-serviceable parts.
The Service Pendant is used with the following leak detectors:
Model 947
Model 948
The warning messages are for attracting the attention of the operator to a particular procedure or practice which, if not followed correctly, could lead to serious injury.
The caution messages are displayed before procedures, which if not followed, could cause damage to the equipment.
The notes contain important information.
Model 960
DRAFT 2/4/02
This equipment is designed solely to be used with the leak detectors listed above. The Service Pendant itself poses no inherent hazard or safety threat to an operator.
However, leak detector operators and service personnel must be aware of all hazards asso­ciated with leak detector operation. They must know how to recognize hazardous and potentially hazardous conditions, and know how to avoid them. The consequences of unskilled, improper, or careless operation of the equipment can be serious. This product must only be operated and maintained by trained personnel.
Every leak detector operator or service person must read and thoroughly understand leak detector operation/maintenance manuals and any additional information provided by Varian Vacuum Technologies. All warnings and cautions should be read carefully and strictly observed. Consult local, state, and national agencies regarding specific requirements and regulations. Address any safety, operation, and/or maintenance questions to your near­est Varian Vacuum Technologies office.

The Service Pendant
The service pendant is used to set up and display parameters for the Model 947, 948 and 960 Leak Detectors. It is a hand-held terminal with a 40-key keypad and a 20 character by 4 line backlit LCD display (see Figure 1). The service pendant is stored in the turret and connects to the leak detector via a six-foot cable that connects to an RS-232 serial port (J1, a 9-pin D sub connector) located inside the lockable turret.
The service pendant is used to monitor and set up:
Reject set points
Crossover pressures
Auto sequence parameters
System setup parameters (such as the value of the calibrated leak)
Ion Source parameters (should only be performed by qualified service personnel)
When the pendant is powered by the 947, 948 or 960, the display indicates the model of the leak detector to which it is connected.
Refer to Model 947, Model 948 Operations Manual or the Model 960 Operations Manual for further information on the operation of the leak detector.

Keypad Functions
Figure 2 shows the service pendant keypad. A glossary of the keys begins on page 8. Table 1 on page 8 explains the keys that perform special functions when entering information. Table 2 on page 8 explains the remaining keys, which are used to input or display data.
To give you a better understanding of how to use the pendant, step-by-step instructions for a few common leak detector functions follow this figure.

Using the Service Pendant – Parameter Examples
Except for numbers and special function keys, most keys have three lines of text—the parameter and two operations.
The function is generally printed in black in the center of the key (for example,
RNG ST
Some functions require the input of a number before the function key is pressed. Other functions, such as queries, do not require any numeric input. When a command or request is successfully completed, the display ends with ok and a line feed. The pendant is ready for the next command.
The operation to be performed on that parameter is printed in either blue (for example, part of the key).
The keys to set the Reject Points and some of the service group keys are the exceptions. On these keys, the operation (SET or SHOW) is the center text.

Figure 3 has four illustrations of the keypad each highlighting a different functional group of keys (Service, System Setup, Operation/Status, and Auto Sequence). As an operator, you will primarily use the System Setup and the Operation/Status keys. We have not included an illustration grouping the general entry keys, such as SHIFT, CANCEL and the numeric keys.
