This document is not intended to replace document 1SCC303022M0201, ZTX series O&M,

which is called out in some cases for further detail. This quick start guide is intended to

help the user power the ATS and make it fully operational with a few simple steps.

1. Transfer switch

2. Embedded ATS control unit and mechanism

3. Dip-switch control interface (HMI) for configuration and automatic operation

4. Slide switch (Hand - Locking - AUTO) for selection of the operation mode

5. Padlocking the automatic transfer switch to prevent automatic and manual operation.

Remark: Slide switch (Hand - Locking - AUTO) has to be in Lockingposition

6. Handle for manual operation

7. Position indication

8. Terminals for control circuit connections

9. Place for Ekip-modules; communication, signaling and connectivity modules

10. Auxiliary contact block mounting location

11. The product identification label

12. Programming port, only for Ekip Programming module and Ekip Bluetooth-modules

About your ZTX series ATS

Zenith ZTX series construction

Zenith ZTX series ATS consists primarily of the TruONE™ power panel and an electrical enclosure. The

TruONELevel 2 power panel integrates switch, mechanism, controller, power supply, HMI, and all

connectivity accessories into one seamless unit. The construction of this transfer switch is outlined

in Figure 1.

Using Ekip Programming and Ekip Connect

(Optional, laptop and Ekip Programming module

required)

Ekip connect is not required because all programming can be done from the HMI. It is, however a

valuable tool for offline programming or rapidly programming multiple ATS with the same program.

With Ekip Programming module and a laptop with Ekip Connect

software, you can view status, set operational parameters, and

configure generator exercisers on the ATS, even without any line

voltage or auxiliary power connected to the panel. This USB

module plugs directly to the HMI. Download the Ekip Connect

software and manual from the QR code or web address at the right.

Note: Auxiliary contacts are very difficult to remove once applied!

Auxiliary contacts will be shipped loose. Use Table 1 and Figure 3 to apply A (NO) and B (NC) contacts

for correct operation. Each source has two separate mounting points capable of holding up to two aux

contacts each for position indication, for a total of four per source. There is no restriction on using

NO, NC, or both in any location.

Energizing

For detailed instructions on installing your enclosed ATS and installing accessories, see sections 9 and 10

of the ZTX O&M manual.

Before energizing the panel:

1. Confirm that installation has been performed by a qualified person and in accordance with NFPA

70 (NEC). Ensure this installation is properly operated and maintained in accordance with the

safety practices of NFPA 70E.

2. Confirm rating label matches the installed application. For location see Figure 1, number 12.

3. Confirm that cables are connected properly and torqued according to label the ATS labeling.

4. Verify that the enclosure ground connection is properly terminated.

5. Confirm that control wiring for engine start is properly terminated to the engine start contact

(located in Figure 1, number 8).

6. Additionally, connect all applicable digital I/O, communications, and auxiliary contact wiring.

7. Flip slide switch (Figure 1, number 4) to AUTO

8. Ensure that all objects and debris are removed from enclosure, and enclosure is closed and

latched.

Auxiliary contacts will be shipped loose. Use Table 1 and Figure 3 to apply A (NO) and B (NC) contacts

for correct operation. Each source has two separate mounting points capable of holding up to two aux

contacts each for position indication, for a total of four per source. There is no restriction on using

NO, NC, or both in any location.

transferring load)

3. On load test: Start/stop on-load test (starts generator then transfers load

Manual and Auto modes.

HMI keypad operation

Auto configure is the first step to take after the panel is initially energized. This function recognizes

the electrical system, then automatically sets all the system parameters: system voltage, frequency,

and phase sequence.

Settings (Optional)

Default settings on the ATS are as shown in Figure 6. To alter settings, simply adjust the position of

the dip switches accordingly. Generator exercisers must be programmed through Ekip Connect 3 with

Ekip Programming module

Confirm Automatic Operation

To put your ATS into Auto mode, confirm the slide switch is in “AUTO” before the enclosure door is

closed. This slide switch overrides the Auto/Manual mode set from the HMI. To place ATS controller in

auto mode, press the auto key on the HMI as in Figure 7. If already in Auto mode, pressing this key will

take the switch out of Auto mode.

Confirm the ATS is in Auto mode by validating that the “AUTO” LED above and to the right of the LCD

screen is solid green.

Figure 7

—

Test

Run an off-load test to verify the ATS-generator control connection. Follow steps in Figure 8. Backup

source (generator) should start and be indicated by solid green LED for secondary source. Repeating this

sequence will turn off generator.

To test ATS-generator auto operation, while in auto mode, simulate a primary source failure by

disconnecting the supply to the primary source. Verify the ATS switches to the backup source

according to set-point and time delay parameters. Re-connect the supply to the primary source. If the

ATS returns to primary source as expected, the ATS function in Auto is validated.
