Startup Databases, retrievable through TACHLINK, contain configurations that
utilize some of the more commonly used setups. By selecting one of the Databases,
the constants are configured and may reduce the setup time and effort. Annex 1
(section 8) contains a table listing the Startup databases. See section 4.2.1.1 for how
5.1. Basic setup
A pump shaft spins at a constant speed of 2000 rpm. A 4”, 30 tooth, 8 Diametral pitch
target is mounted to the shaft. The user wants to set the tachometer to alarm if the shaft
aft speed returns to 1980
isplay.
5.1.1. Material Requirements
• 1 TACHPAK 10 (TP10): Use for speed
• 1 AI-TEK Passive Sensor
5.1.2. Connections
Instrument configuration can be done on the bench and tested using Verify and
Diagnostics. Connections can then be made as follows:
• Connect power per section 3.4.2.
• Connect sensor to TP 10 per section 3.4.1.
• Connect alarm Relay 1 TP10 to speed alarm per section 3.3.1.
