Page 11: Cut-Out Details
1.5.4 Cut-out details Figure 4 – Case dimensions and Cut-out details The unit may be mounted in a panel of any thickness up to a maximum of 6 mm (0·25in). Leave enough space behind the instrument to allow for bends in the connection cables. As the front of panel enclosure conforms to IP52, it is protected from dripping water. - Page 12 Fusing This unit must be fitted with external fuses in voltage and auxiliary supply lines. Voltage input lines must be fused with a quick blow fuse 1 A maximum. Auxiliary supply lines must be fused with a slow blow fuse rated 1 A maximum.

Page 13: Pm-Progress Modbus Protocol Implementation
A total maximum length of 3900 feet (1200 meters) is allowed for the RS485 network. A maximum of 32 electrical nodes can be connected, including the controller. The address of each PM-Progress can be set to any value between 1 and 247. Broadcast mode (address 0) is not supported. -
Page 14: Input Registers
1 stop bit if parity is used; 1 or 2 bits if no parity Data Coding All data values in the PM-Progress are transferred as 32 bits IEEE 754 floating point numbers, (input and output) therefore each PM-Progress value is transferred using two MODBUS Protocol registers. All register read requests and data write requests must specify an even number of registers. -

Modbus Protocol transactions involving floating point numbers. It is perfectly feasible to change PM-Progress set-up using a general purpose Modbus Protocol master, but often easier to use the PM-Progress display or PM-Progress configuration software, especially for gaining password protected access. - Page 18 Once the required changes have been made to the protected parameters the password lock should be reapplied by following one of these actions: Allowing the password to timeout Writing any value to the Password Lock register Power cycling the instrument.

Page 21: Troubleshooting
3.4 Troubleshooting Start with a simple network, one master and one slave. With PM-Progress this is easily achieved as the network can be left intact while individual instruments are disconnected by removing the RS485 connection from the rear of the instrument. -
Page 22: Maintenance And Safety Requirement
4 Maintenance and safety requirement 4.1 Maintenance In normal use, maintenance operations are pretty simple. As appropriate for service conditions, isolate electrical power, inspect the unit and remove any dust or other foreign material present. Periodically check all connections for screw tightness and make sure there is no corrosion, particularly if vibration is present. The front of the case should be wiped with a dry cloth only. -
