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

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.

1. Lamp test: Turns on all LEDs simultaneously to confirm all are functional
2. Off load test: Start/stop off-load test (starts generator without
transferring load)
3. On load test: Start/stop on-load test (starts generator then transfers load
when source OK)
4. Bypass time delay: Bypasses ongoing time delay
5. Auto (Alarm reset): Resets alarms (if any). If no alarms, toggles between
Manual and Auto modes.
6. I ON: Operate* switch to I position
7. II ON: Operate* switch to II position
* Slide switch (Figure 1, number 4) must be in Auto, and controller mode (Figure 3

HMI keypad operation
Figure 4

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.
