• XSEL Controller P/Q/PCT/QCT Type Operation Manual Nineteenth Edition. • CAUTION Operator Alarm on Low Battery Voltage This controller is equipped with the following backup batteries for retention of data in the event of power failure: [1] System-memory backup battery For retention of position data, global variables/flags, error list, strings, etc. [2] Absolute-encoder backup battery (optional) For retention of rotation data (when an absolute encoder is used) Since these batteries are not rechargeable, they will be eventually consumed. • Therefore, it may cause early degradation on the internal components if turning on/off of the power and turning on/off of the drive power due to emergency stop input are conducted frequently.

Contact IAI in case it is necessary to establish a system to allow frequent turning on/off of the power inevitably. • For a controller with expanded CPU unit memory, use the PC software or teaching pendant of an applicable version as specified below. Teaching tool Version XSEL PC software V7.2.0.0 or later Teaching pendant SEL-T/TD V1.01 or later [How to check if the controller memory has been expanded] Check in the PC software (Ver.

• Safety Guide Safety Precautions for Our Products. • Operation Description Description Transportation When carrying a heavy object, do the work with two or more persons or utilize equipment such as crane. When the work is carried out with 2 or more persons, make it clear who is to be the leader and who to be the follower(s) and communicate well with each other to ensure the safety of the workers. • Operation Description Description Installation (2) Cable Wiring and Start for connecting between the actuator and controller, and for the teaching tool. Do not scratch on the cable. Do not bend it forcibly.

Do not pull it. Do not coil it around. Do not insert it. Do not put any heavy thing on it. Failure to do so may cause a fire, electric shock or malfunction due to leakage or continuity error. • Operation Description Description Installation (4) Safety Measures and Start When the work is carried out with 2 or more persons, make it clear who is to be the leader and who to be the follower(s) and communicate well with each other to ensure the safety of the workers. When the product is under operation or in the ready mode, take the safety measures (such as the installation of safety and protection fence) so that nobody can enter the area within t.

An in-depth phylogenetic analysis of protein sequences showed that this family composes a distinct clade, which shares a last universal common ancestor with DNA ligases I. Thaliana, as well as the partially assembled genomic data of Medicago truncatula L. Moreover, hydrophobic cluster analysis and 3-dimensional modelling allowed us to map two conserved domains within these DNA ligases I-like proteins. And Brassica spp., allowed us to identify a new family of ATP-dependent DNA ligases that are found only in the Viridiplantae kingdom. Brendel br 301 manual transmission system. In silico sequence studies indicate that these proteins have distinct physico-chemical properties when compared with those of animal and fungal DNA ligases.

• Operation Description Description Trial Operation When the work is carried out with 2 or more persons, make it clear who is to be the leader and who to be the follower(s) and communicate well with each other to ensure the safety of the workers. After the teaching or programming operation, perform the check operation one step by one step and then shift to the automatic operation. • Operation Description Description Maintenance When the work is carried out with 2 or more persons, make it clear who is and Inspection to be the leader and who to be the follower(s) and communicate well with each other to ensure the safety of the workers. Perform the work out of the safety protection fence, if possible. • Alert Indication. • Table of Contents Introduction..1 Part 1 Installation..3 Chapter 1 Safety Precautions..
