18. Enable or disable Channel 2 Loopback by using DIP switch SW3-8.
Place SW3-8 in the UP position to disable Channel 2 Loopback, or in the DOWN
position to enable Channel 2 Loopback. Unless otherwise specified at time of
order, SW3-8 is set in the UP position at the factory.
19. Select Channel 1 Loop Current by using DIP switch SW6-5.
Place SW6-5 in the ON position to select a loop current of 41 mA, or in the OFF
position to select a loop current of 20 mA. Unless otherwise specified at time of
order, SW6-5 is set in the OFF position at the factory.
20. Select Channel 2 Loop Current by using DIP switch SW9-5.
Place SW9-5 in the ON position to select a loop current of 41 mA, or in the OFF
position to select a loop current of 20 mA. Unless otherwise specified at time of
order, SW9-5 is set in the OFF position at the factory.
21. Select the Channel 1 Ring Delay by using switches SW6-6 and SW6-7.
There are four types of Ring Delay that can be selected. Refer to Table 5 to
determine how the switches are set for each of type of Ring Delay. Unless
otherwise specified at time of order, SW6-6 and SW6-7 are set in the OFF position
at the factory to select No Ring Delay.
22. Select the Channel 2 Ring Delay by using switches SW9-6 and SW9-7.
There are four types of Ring Delay that can be selected. Refer to Table 5 to
determine how the switches are set for each of type of Ring Delay. Unless
otherwise specified at time of order, SW9-6 and SW9-7 are set in the OFF position
at the factory to select No Ring Delay.
If Module Adapter MA-302 or MA-302A are being used as an interface to the
VF-16B Module, in steps 23 through 26 set the Ring Voltage and Ring Voltage
Offset to the factory default, otherwise proceed as follows:
23. Select the Channel 1 Ring Voltage by using switches SW6-1 and SW6-2.
There are four levels of Ring Voltage that can be selected. Refer to Table 4 to
determine how the switches are set for each level of Ring Voltage. Unless otherwise
specified at time of order, SW6-1 and SW6-2 are set in the OFF position at the
factory to select a Ring Voltage of 40.5 volts.
24. Select the Channel 2 Ring Voltage by using switches SW9-1 and SW9-2.
There are four levels of Ring Voltage that can be selected. Refer to Table 4 to
determine how the switches are set for each level of Ring Voltage. Unless otherwise
specified at time of order, SW9-1 and SW9-2 are set in the OFF position at the
factory to select a Ring Voltage of 40.5 volts.
25. Select the Channel 1 Ring Voltage Offset by using switch SW6-3.
There are two levels of Ring Voltage Offset that can be selected. Refer to Table 4
to determine how the switches are set for each level of Ring Voltage Offset. Unless
otherwise specified at time of order, SW6-3 is set in the OFF position at the factory
to select a Ring Voltage Offset of 0 Vdc.
