10.1.3 Amplifier Replacement
IMPORTANT
In case of amplifier replacement, it is necessary to perform the parameter resetting.
For parameters, refer to Chapter 6: Parameter Description.
(1)Turn off the power.
(2)Remove the cover.
(3)Remove all cables that are connected to the terminals.
(4)Remove the display unit as described in Section 10.1.2.1.
(5)Loosen the amplifier assembly’s four screws while supporting it with your hand (See Figure 10.1.3).
(6)Pull the amplifier assembly straight out.
(7)When reassembling the amplifier assembly, return it to its original position and secure it in place using the reverse procedure to that described above.

10.2 Setting of Switches
10.2.1 Setting of Burnout Switch
The burnout function sets the direction of current output in situations where the CPU has become damaged. Upon shipment from the manufacturing plant, the burnout direction is set to High (i.e., 25 mA); however, in cases where the optional code C1 has been specified, the output direction will be set to Low (i.e., 0 mA).
Modification of the burnout direction must be carried out using the setting switch from the amplifier’s CPU board (i.e. Switch 1) (See Figure 10.1.4).

NOTE
On the amplifier’s CPU board, the burnout setting switch (i.e., Switch 1) and the write protect switch (i.e., Switch 2) are located adja- cent to each other. Accordingly, special care should be taken when making switch settings.
