1. Note about configuration values are entered from left to right on the display For example to enter the number 15 the user would press the up arrow key once so that a 1 is displayed The user would then press the left arrow key once so that a 10 is displayed Next the user would press the up arrow key five times so that a 15 is displayed The number that will be modified will always flash on the display Configuration Deviation Band The Deviation Band menu screen will display the number of millivolts that the deviation band alarm is set for default 10 mV Pressing the ENT key will enable the user to modify the deviation band value Once the ENT key is pressed the rightmost number will begin flashing Pressing the up arrow key will reset the value to a 1 Pressing the up arrow key again will increment this value by one Enter the new value as desired Pressing the ENT key will set the entered value Pressing the CLR key will reset the value to the last set value Pressing the NEXT key will display the A arm Delay menu screen Pressing the PREV key will display the initial display Example The following example will show how to set the deviation band from a value of 50 mV to a value of 35 mV Press the ENT key The 0 in the 50 will begin flashing Press the up arrow key three times so that a 3 is displayed Press the left arrow key once so that a 30 is displayed Press the up arrow key five times so that a 35 is displayed Press the ENT2.

11. y e Safety Symbols Various symbols are used on the instrument They have the following meaning Caution refer to the accompanying documents e Grounding of the temperature sensor shield In some installations it is common practice to replace the temperature sensor while the controller is still powered up Under these conditions as additional protection against electric shock it is recommend that the shield of the temperature sensor be grounded Do not rely on grounding through the framework of the machine e Installation requirements for EMC To ensure compliance with the European EMC directive certain installation precautions are necessary When using relay or triac outputs it may be necessary to fit a filter suitable for suppressing the emissions The filter requirements will depend on the type of load For typical applications it is recommended to use Schaffner FN321 or FN612 e Routing of wires The wiring for the low voltage DC and particularly the sensor input should be routed away from high current power cables This will minimize the pick up of electrical noise When it is impractical to do this use shielded cables with the shield grounded at one end M4560 Model 9120 RPS Page 3 of 11 M4560 Model 9120 Redundant Probe System Wiring Terminals nd in n tad 9120 Wiring Terminations 5 SLAVE1RS485 16 RELAY OUT 8 NO 6 SLAVE 1 RS485 17 DIGITAL IN 1 7 RELAY COMMON 18 DIGITAL IN 2 8
