1 — OVERVIEW
e Curtis Electronic Code Switch (ECS) is an operator identication keypad. e ECS ensures
that only authorized users can operate a vehicle. e ECS supervisor denes the authorized users.
Authorized users can log on by entering a user ID and PIN code or by swiping an RFID tag.
e ECS can be integrated into vehicle systems with or without a CANbus. e ECS is designed for
use in applications such as material handling vehicles, MEWP (Mobile Elevating Work Platforms),
golf carts, ICE vehicles, and many others.
e following list summarizes the ECS’s key features:
• A Normally Open (NO) relay that is opened and closed by CAN messages or by users logging
on and o.
• Machine power control through authorized RFID tag and PIN code access or CAN commands.
• Easy to integrate with vehicle systems:
–CAN-based systems: CANopen implementation with an optionally connected CAN
termination resistor. Supports CAN baud rates from 100 Kbps to 1 Mbps.
–Non-CAN systems: e output relay changes state when an authorized user logs onto
the ECS.
• Pass-through mode, which is for applications in which another CAN device can receive
keypad entries and RFID tag swipes.
• Supports ISO 14443A RFID tags.
• Allows up to 100 users.
• Status LEDs and a buzzer conrm keypad entries and provide diagnostic information.
• Automatic log o based on the interlock state and a congurable timer.
• You can use the Curtis Integrated ToolkitTM (CIT) or the Curtis 1313 handheld programmer
to change parameters, monitor real-time data, review and clear the fault history, update
rmware, and perform other diagnostic and application development tasks.
• Operates in demanding conditions, with an operational temperature range of –40° to +70°C
and electronic components sealed to IP65.
• CE compliance, UL recognition, and ROHS 3 compliance ensure compatibility with global
regulatory safety.
Note: For technical support, contact the Curtis distributor or the Curtis sales and support oce in
your region.

KEYPAD
e ECS keypad consists of buttons for the numbers 0–9, as well as and buttons:
• e button is used to submit entries. For example, press aer you enter a menu number.
• e button is used to perform various tasks such as logging on and o, clearing data, and
returning to the previous menu.
LEDs
e ECS has green and red LEDs that indicate information such as the current menu, status, and
fault codes. e following table summarizes the typical usages of the LEDs:
ECS OperationLEDs
The ECS is idle.
A user is logged on to operate the vehicle.
A fault occurs.
The supervisor is on the Supervisor Management

3 — USER OPERATION
e ECS ensures that only authorized users can access a vehicle. If you are authorized, the ECS
supervisor will provide you with a user ID and PIN code, an RFID tag, or both.
e following sections describe how to use the ECS to operate a vehicle and to create or change your
tag, PIN code, and/or user name code.
OPERATE A VEHICLE
To operate a vehicle equipped with the ECS, log on by taking one of the following steps:
• Place your user tag in front of the ECS.
• Enter your user ID and PIN code, then press .
Note: If your user ID is 1–9, enter 0 before the digit. For example, if the user ID is User 3, enter 03.
If your tag or your user ID and PIN code are valid, the buzzer sounds the Success sound and the
green LED remains on without ashing. You can now operate the vehicle.
RedGreen
You remain logged on until you either log off, the interlock switch is off for longer than the
programmed timeout interval, or another operator swipes a tag.
Once you have nished operating the vehicle, log o by pressing and holding until you hear the
Return sound and the green LED starts ashing.
RedGreen
USER MANAGEMENT MENU
e User Management menu allows you to add or change your PIN code, tag, and/or user name
code. When you are on the User Management menu, the red LED remains on without ashing and
the green LED is o.
RedGreen
e User Management menu contains the following menus. To access a menu, press its menu number:

outputs (I/Os).
INSTALLING THE ECS
To install the ECS, snap-fit it into the desired location, using 2.0–4.0 mm snap-in fingers.
The location should be carefully chosen to keep the ECS clean and dry. Figure 1 shows the

PRECHARGE
To suppress arcing across the relay contacts when the relay closes, the ECS uses a current-limited
precharge circuit to power the devices connected to Relay NO. e relay closes when the Relay NO
voltage reaches 90% of the Relay COM voltage; if the relay doesn’t close, a Precharge Fault occurs.

When the ECS commands the relay to close or open, the Relay State parameter indicates the
relay’s state:
• When the relay closes, the Relay State value changes in this order: 0, 1, 2, 3, 4, 5.
• When the relay opens, the Relay State value changes in this order: 5, 6, 8, 0.
e Relay Work Mode parameter species whether logging on or CAN commands engage the relay.
ere also are parameters for conguring the relay’s pull-in and holding voltages; see Relay Menu.
INTERLOCK
When the interlock state is o and the logo interval has expired, the ECS automatically logs the
user o. e logo interval is specied with the Logo Time parameter.
Note: e automatic logo can be disabled by setting Logo Time to 0.
e interlock signal can be controlled with either a switch, such as a seat switch, or RPDO1. e
Interlock Type parameter species the interlock signal’s source.
If the vehicle uses an interlock switch, connect the switch to pin 2. When a switch is used, the
interlock’s input voltage ranges from 0V to the B+ voltage. e interlock input is active high; the
interlock state is o when the interlock input’s voltage is below the voltage specied with the Interlock
High reshold parameter.
Note: For information on the interlock parameters, see Control Menu.
CANbus
To connect the ECS to the CANbus, connect CAN Low and CAN High to pins 5 and 6, respectively.
Use twisted-pair wiring to minimize the likelihood of picking up a voltage bias on only one signal.
Pin 1 provides access to an internal 120Ω terminating resistor. To enable the resistor, connect CAN
High (pin 6) to pin 1.
e ECS includes parameters for items such as the baud rate, heartbeat rate, node ID, and PDOs. For
more information, see CAN Interface Menu and CANopen Communications.
CALIBRATE THE ANTENNA
Aer the ECS is installed, calibrate the antenna so that the ECS automatically detects the best channel
for RFID recognition. You can calibrate with either of the following:
• e AM Base Calibration parameter.
• e keypad; see the Calibrate the Antenna section.

5 — THE ECS SUPERVISOR AND USERS
e ECS supervisor is responsible for authorizing users to log on to the ECS. e supervisor authorizes
users by creating PIN codes and/or tags for user IDs. Aer the supervisor creates a user, the user can
log onto the ECS by swiping the tag or entering the user ID and PIN code.
e supervisor can delete users. When a user is deleted, the user’s PIN code and/or RFID tag are
deactivated and the user can no longer log on to the ECS.
e ECS provides 100 user IDs. e supervisor’s user ID is 00. e remaining user IDs, which range
from 01 through 99, are for users.
The default supervisor PIN code is 123456. For security reasons, change the supervisor’s PIN code
CAUTION
as soon as possible.
e following considerations apply to supervising users:
• e default PIN code for users is 1234. Aer the supervisor creates a PIN code for a user ID,
the user should specify a dierent PIN code.
• Aer the supervisor creates a tag for a user ID, the user can create a PIN code.
• Aer the supervisor creates a PIN code for a user ID, the user can create a tag.
• e supervisor can remove a user’s tag while preserving the user’s PIN code, and vice versa.
• e supervisor logs on with the ECS keypad.
• e supervisor manages users with the keypad or with a Curtis programming device, as
described in the following topics:
–Supervisor Operation with the Keypad
–Manage Users with Curtis Programming Devices
Note: e supervisor can also use the keypad to update some parameters and calibrate the
antenna eld strength level.
USER STATUSES
Each user ID has a user status. e user status indicates whether and how the user can access the
ECS. User statuses are identied by numbers and are described in the following table:
Table 4 User Statuses
User StatusDescription
1The user is not authorized to access the ECS.
2The user only has a PIN code.
3The user only has a tag.
4The user has both a PIN code and a user tag.
