Step 6: External Supplies
If the encoder’s supply was not set in Step 3, it can be set in this menu, too. If there are minimum
and/or maximum supply-current trip points, set these now. Otherwise, leave at their default
values (recommended).
Step 7: Outputs.
Here is where the output frequency for drivers 2–5 is set, and whether the “driver checks”
are individually enabled. Using Figure 6 as the example, enable the driver checks for Driver 1
(Proportional “lower” valve), Driver 2 (EM Brake), Driver 3 (Load-hold valve), and Driver 5 (Main).
Since Driver 4 is not used, its Driver 4 Checks Enable parameter remains at 0 (O). Within this menu,
select whether or not to use the Coil Supply Start Up Checks feature (On/O).
See Programmer » Controller Setup » Outputs » menu.
Step 8: IO Assignments
As noted in Chapter 2, the controller does not have pre-defined (or fixed) coil drivers or switch
assignments. e analog inputs are congurable as digital inputs and vice versa. e coil drivers are
assignable as digital (switch) inputs. In this step, set the application’s principle coil drivers, switch inputs,
and the common analog control sources. e order of setting these parameters is not important.
See Programmer » Controller Setup » IO Assignments
a) Coil Drivers. Assign the driver to these common coils as applicable.
i) Set the Main Contactor Driver as per the application’s main-contactor wiring. Figure 6 uses
Driver 5.
ii) Set the EM Brake to the application’s EM Brake wiring. Note: driver 2 can supply up to 3A,
hence it will typically be the EM Brake driver as illustrated in Figure 6.
Note: Driver 1 is a high frequency driver, intended for proportional valves (e.g., a lowering
valve).
Driver 4 is a standard driver.
e 5 drivers only have the driver’s checks as an associated parameter. All other
options are via VCL.
Contact the Curtis distributor or regional Curtis oce for help with the coil drivers
or their application.
See Programmer » Controller Setup » IO Assignments » Coil Driver
b) Switch Assignments. Based upon the application’s wiring, assign each of the menu’s parameters
to a specic input (switches in these examples).
Refer to Figure 6 as a guide:
Interlock Input Source = 5
Forward Input Source = 7
Reverse Input Source = 8
EMR Switch Source NO = 9
EMR Switch Source NC = 13
Li Input Source = 10
Lower Input Source = 11
See Programmer » Controller Setup » IO Assignments » Controls
Note: e status of any switch, On or O, is visible in the associated sub-menu.
