Intermatic GM40AVE Series General Purpose Electronic Commercial Time Switches

Important Safety Information

WARNING:

• To avoid fire, shock, or death, turn off power at the circuit breaker and test that power is off before wiring.
• Read instructions completely before installation and retain for future reference.
• Observe all national and local electrical and safety codes.
• Disconnect power when servicing or changing loads.
• Alterations or modifications to the device will void the warranty.
• For outdoor locations, rain-tight or wet location conduit hubs that comply with the requirements of UL 514B Conduit, Tubing, and Cable Fittings, must be used.

Installation Instructions

1. To avoid fire, shock, or death, turn off power at the circuit breaker and test that power is off before wiring.
2. Open door and remove the interior protective cover by releasing the spring latch (see Figure 1: Spring Latch).
3. Remove the printed circuit board by releasing the spring latch holding the bottom of the board (see Figure 2: PCB Latch).
4. Select knockouts to be used. Remove the inner 1/2” knockout by inserting a flathead screwdriver in the slot and carefully punch the knockout loose. Remove slug. If a 3/4" knockout is required, remove the outer ring with pliers after removing the 1/2” knockout. Smooth edge with knife, if necessary.
5. Place the enclosure in the desired mounting location, and mark the three mounting holes (refer to Figure 3 for dimensions). Install the top screw first with one of the supplied spacers, and then hang the enclosure by the keyhole. Drive the remaining two screws at the bottom of the enclosure through the mounting holes while passing each screw through one of the supplied spacers and into the wall.
6. Connect conduit hubs to conduit before connecting the hubs to the enclosure. After inserting hubs into enclosure, carefully tighten hub lock nut. Do not overtorque.
7. Replace printed circuit board making sure to engage spring latch at the bottom of the PCB.
8. Wire in accordance with national and local electrical and safety codes (see wiring diagrams on page 3).
9. Grounding: Terminate all ground wires to the ground lug inside the case at the bottom of the enclosure.
10. Replace interior protective cover.

Programming Instructions

The installer should refer to the supplemental instruction manual included with this unit for information regarding setting the time, symbols, keys, and programming.

AC voltage must be present at terminals L1 and L2/N for the relays to operate and the status indicator to change from OFF to ON.

Application

The GM40AVE Series Time Controls are universal, electronic time switches designed for general purpose commercial applications. The control operates on any AC voltage from 120VAC to 277VAC. The mechanism is mounted in an indoor/outdoor enclosure and has been designed for the control of lighting, heating, air conditioning, pumps, motors, or general electrical circuits in residential, commercial, industrial, and agricultural facilities.

Specifier's Guide

Furnish and install an Intermatic GM40AVE Auto-Volt Series with digital programmable timer with battery backup. The Auto-Volt input voltage range shall be 120VAC to 277VAC, 50 / 60 Hz. All units shall incorporate two isolated sets of SPDT contacts that are each rated at 40A, 2 HP @ 277V. LED indicators shall provide Power and Status feedback. Enclosure shall be UL Type 3R, suitable for indoor or outdoor installation. Timers with battery backup will automatically keep time and do not require resetting after a power outage.

Basic Operation

Wiring and load control can be verified by manually turning the unit ON and OFF using the override (OVR) + key.

Automatic Voltage Selection From 120 VAC to 277 VAC

The GM40AVE features:

• A new UL Type 3R enclosure suitable for indoor or outdoor installation.
• Built-in battery backup that automatically keeps time and does not require resetting after a power outage.
• Yellow and Green LED lights indicating Power and Status.
• Large screw terminals for easy wiring up to #8 AWG.
• Large ground lug termination.
• An easy-to-read LCD screen.
• An easy and simple programming interface with large buttons.
• One-minute intervals for programming.
• 40 Amp rated contacts.
• A moisture-resistant conformal coated board.

It also points out the UL Type 3R enclosure, easy-to-read LCD, large buttons, one-minute intervals, 40 Amp contacts, and moisture-resistant conformal coated board.)

Terminal Designations

WARNING: This Time Switch is designed to control one or two single phase loads. Do Not use to directly control three phase loads. Consult a qualified electrician if you are required to control three phase equipment.

NOTICE:

• The circuit conductors shall have an ampacity not less than the maximum total load to be controlled.
• For all connections, use min. 8 AWG wire for 40 A loads or 10 AWG for 30 A loads, min. 90 °C (194 °F) rating.
• Over current protection shall have an interrupting rating sufficient for the application control circuit voltage and the total load current of the equipment being controlled.
• A fuse or circuit breaker shall be connected in series with each ungrounded conductor (and shall be able to simultaneously open each conductor).
• Jumper wires are not included.

(Description of Terminal Designations diagram from page 3: The diagram illustrates the terminal layout on the timer, labeled as TIMER, with connections for L1, L2/N, NC, NO, COM, NC 2, NO 2, and COM2.)

Typical Wiring Diagrams

120 VAC One Load: Connect a jumper wire (J1) between L1 and COM to control a single phase 120 VAC load.

120 VAC Two Loads: Connect a jumper wire (J1) between L1 and COM, and a second jumper wire (J2) between COM and COM2, to control two single phase 120 VAC loads. NOTICE: Ensure the combined amperage of Load 1 and Load 2 does not exceed the limits of the feed circuit.

240 VAC One Load: Connect a jumper wire (J1) between L1 and COM, and a second jumper wire (J2) between L2 and COM2, to control a single phase 240 VAC load.

277 VAC Two Loads: Connect a jumper wire (J1) between L1 and COM, and a second jumper wire (J2) between COM and COM2, to control two single phase 277 VAC loads. NOTICE: Ensure the combined amperage of Load 1 and Load 2 does not exceed the limits of the feed circuit.

Troubleshooting Guide

WARNING: Some terminals in the Time Switch may be energized even if the yellow and green LED indicators are OFF. Check all terminals and wires with an appropriate voltage checker before touching.

PROBLEM: LOAD (Lights/Pumps/Motors, etc) will NOT turn ON or OFF

1. Verify that all wiring connections are correct (Refer to wiring diagram on page 3).
2. Check the YELLOW Power LED. If ON, it indicates that power is applied to the GM40AVE. NOTE: The relays in the GM40AVE will not operate if AC power is not present.
3. Check the status indicator on the LCD screen. If it indicates OFF, press the + key one time. This will turn both loads ON.
4. Check for correct voltage at terminals (NO) and/or (NO2).
5. Check the status indicator on the LCD screen. If it indicates ON, press the + key one time. This will turn both loads OFF.
6. Check for correct voltage at terminals (NO) and/or (NO2).
7. Verify that the programming is correct. Refer to the supplemental programming instruction manual included with this unit.
