Step 7: Outputs
Here is where the output frequency for drivers 2–5 is set, and the “driver checks” are individually
enabled. Using Figure 13 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 » Coil Supply Start Up Checks
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
8.1 Coil Drivers. Assign the driver to these common coils as applicable.
8.1.1 Set the Main Contactor Driver as per the application’s main-contactor wiring. Figure
13 uses Driver 5.
8.1.2 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 Figures 12–15.
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
8.2 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 wiring diagrams (Figures 12–15) 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
* Set according to the application which may not match the default settings.
Note: e status of any switch, On or O, is visible in the associated sub-menu.
See Programmer » Controller Setup » IO Assignments » Switch Status
